Solidworks - Science topic

Hello everyone,

I am currently working on a case involving Cardiovascular disease using FSI (Fluid-Structure Interaction). I have an artery in an STL file. However, when I created a shell for the artery to represent the arterial wall in the mechanical simulation, it ended up consisting of multiple parts, making it difficult to select and to apply pressure on the surface.

Is there any way to merge the facets on the wall and the inlet into a single surface?

Thank you.

Hello,

I am currently working on a packed column model in SolidWorks. The column comprises a packing material consisting of numerous beads (or other packing types such as Raschig rings) initially positioned outside and above the column. To achieve a random packing configuration, I utilized SolidWorks Motion Study. By defining contacts between parts and enabling gravity forces, the beads descend and fill the column randomly, as depicted in the attached file (including the assembly, parts, and screenshots). Now, I aim to maintain the positions of these beads once I transition from the Motion Study tab to the Model tab. Does anyone have a solution for this?

Thank you.

When I draw parts on solidwork and extrude it then the part is not visible, only shadow view is there. How to fix this issue?

Hi there, i have a solidworks based final year project, mainly flow simulation and FEA analysis, i have made a wind tunnel for my wind turbine which is sealed from all the sides, both sides with seperate lids, and when i try to do the flow simulation, the computational domain does not fall on the lids (it does not recognize the lids) it forms on the wind turbine or the assembly, and when i try to manually extend the computational domain on to the lids, this error occurs " Face<1>@LID7-1 is not laying on the boundary between solid and fluid region error

Hello research community

I have been stuck in the process of simulating the deformation that would occur in the collision of two specific objects in a given scenario. But I have only obtained a result similar to what I am looking for when carrying out the fall impact simulation, and only considering one of the two objects.

Doing some research, I found that something similar to what I'm looking for can be achieved by doing a non-linear simulation of an assembly model, but I can't figure out how to display the result of deformation and motion animation (also, I doubt I'm setting up the simulation properly, since it is the first time that I use this function of the software)

Could someone explain to me the proper way to achieve what I'm looking for using this specific software?

Thanks

How to design flow focusing point using solid work for micro fluidic device?

I want to create a geometry/feature where the roller is pinching on the pipe rather than going through it (as shown in attached image).

Hello,

I am writing a paper for my university. I would like to compare the algorithms used in the above mentioned softwares to see why each software results in different topology optimized results.

As far as i know, SolidWorks uses Tosca

i would appreciate any help.

thank you and regards

Hello everyone,

I have been trying to simulate a 'simple' coil consisting of 4 connected springs with a thin circular (D=0.072mm) in Maxwell 3D. These four connected springs make a rectangle (top view) I have tried several attempts on modeling the coil in other CAD softwares and importing them into Ansys Electronics Desktop. Here is the list of attempts I made:

1- Modeling in Maxwell 3D and uniting the springs together to generate one single body - Result: current leaks to the air

2- Modeling in Solidworks and importing as .stp .stl .igs into EDT - Result: Cannot handle thin geometry (the coil will no longer have ciruclar geometry so cannot even apply a current to a terminal)

3- Modeling in NX and importing as .stp. .stl .igs into EDT - Same problem

Modeling one single spring and 2 of them connected to each other (attempt nr 1) did not give me error and 'Validation and Analyse all' was a success. But where I connected 3 or 4 of them, Ansys Electronic Desktop is giving me an error when 'Analyse all' is happening about current leak to the air which is not that straight forward to understand what's wrong, although the Validation goes well.

I also tried to model it in Design Modeler, it's interesting that first spring gets imported very well but the ones connected to it will have messed up geometry and at the end this one body geometry cannot be verified in Maxwell 3D (2 steps for simulation: Validation and Analyse all)

I would be extremely gladto be helped with this very problem and my main question is: does Ansys have hard time understanding and simulating such thin and fine geometry? is this the main reason? and eventually, what's the way out. I believe the main problem here is that I don't know what's exactly wrong. i.e. What does the current leak to the air mean? and where this current leak is taking place so I can modify my model. As a final comment, I tried both ways, open loop and closed loop.

Thanks, any comment is appreciated!

I am using MATLAB and Sigma Plot for graphs plotting, Microsoft Visio for 2D drawings and Solid Work for 3D drawings. However, I want to try some new software that results good quality.

Your recommendation will be highly appreciated.

List the various methods to learn 3D modeling designing using Solidworks.

Dear researchers,

What is the difference between software:

1- Abaqus and Ansys

2- Catia and Solidworks

3- Mastercam and Topsolid

I am using Solidworks for my design. is there any software where designing forging die becomes easier?

Actually I made 2D model in Solidworks, then I imported that 2D model in ANSYS FLUENT, but after meshing it changed to 3D model . Then in Setup it's locked to 3D , although I want 2D simulation. Kindly HELP ME TO TACKLE THIS PROBLEM!?

I am working on a project making an atmospheric water harvester out of a bio~inspired surface and we are wondering what a good simulation software is to analyze water condensation on surfaces and micro structures. We are hoping to simulate how water condenses on our micro structure model (which is currently designed in Solid Works).

Would greatly appreciate some insight to this.

Wishing you all the best and good health

Research Engineers at the University of New Mexico (UNM) are teaming with UNM Biology scientists to study the performance, distribution and food potential of greenhouses (GH). The work, which is being funded by grants, includes a goal to develop a thermodynamic model that can be used to 1) model the energy performance of different GH designs in the same climate and 2) to model the performance of the same GH design in different climates. Such a model would be used to develop geographic potential of various greenhouse designs in the world along with the associated food production potential.

We are seeking other researches who are working on similar modeling efforts and might be interested in sharing information. We are leaning toward using TRNSYS because of its library of routines, but we are open to other approaches. e.g., Anthony Menicucci, Res Assoc Prof, UNM ME, thinks that Solid Works would also work for a simple model. Comments? Collaborators?

I am a beginner in simulations. I want to simulate the current density in a fiber-reinforced polymer foam. However, I don't have access to COMSOL Multiphysics. Is there a free alternative to it that works well enough?

I have a rather simple geometry consisting of a single lap joint of two sheets, to which I added some pins to increase the strength to fracture.

I initially made the parts in Solidworks and them exported them in a step file.

The problem now is that, every time I try to partition the parts to make them meshable, Abaqus takes hours to do so, or it just closes after some time.

Has anyone encountered similar problems?

I dont know if it is related to my geometry, the type of export file from solidworks, abaqus, etc...

Analysis using simulation software (Ansys/Solidwork) to determine the stress deflection and vibration condition on the unit.

Hi all, 

I have an assembly model that I have already meshed in a different software. When I open it in Mechanical APDL, each mesh element is recognised as a surface body, so I have 15000 surface bodies for what should be 1 body (see image attached).

In Solidworks, I have tried converting each part as a solid using "Convert to Solid". 

In ANSYS Design Modeller, the bodies come up correctly as one solid. Some parts were split up into solids and surfaces, but I used "Tools > Form New Part" to combine them. Nevertheless, in Mechanical APDL they are still recognised as surface bodies from the mesh elements. 

How can I get ANSYS Mechanical APDL to recognise each part as one solid? 

Thanks in advance.

Hi Everyone,

I have an assembly parts that mated together. the bolt connector is defined to hold them together. There are 4 parts that been bolted together which is washer (solid element), Sleeve (shell element), Frame tube (shell element) and connector (solid element).the shell element is defined with thin and middle to surface offset.

the geometry itself already been validated using clearance verification and no gap between each of the mated parts.

local contact (no penetration) is defined for each part by surface to surface contact. the default setting of 10% gap to consider contact and 1% to stabilize the area if the gap remain unchanged. the global contact is set as default as bonded.

both end is defined as fixed which no translation and rotation.

bolt connector is defined with advance bolt series option since the assembly has more than 2 parts.

the issues that haunting me is

1) I am getting a unrealistic high stress at the sleeve(shell) and washer parts when using mixed mesh element. Also, the stress distribution at the sleeve and washer is not as expected. However, when all those parts is converted to solid elements the "Abnormal bolt pretension is detected" is disappeared. the results and stress distribution seems more realistic with solid element mesh compared to mixed mesh (solid and shell). Since the sleeve and frame tube is a circular with 4mm thickness , by theory it is more precise to treat these parts as shell. So I wanted to produce study with mixed mesh element.

after try a few options suggested on the internet I am still not able to solve this issue.

any experts able to guide on the setup to find what is wrong with y setup.

attached is the simulation setup file for review.

#FEA

Hello. I'm working on my study in orthodontic department of dentistry.

I'm trying to figure it out how the stress distribution and tooth movement would be presented when wire is engaged in crowded teeth.

I'm going to use software for finite element method, such as ANSYS or Solidworks etc..

I've watched many videos but every simulation starts with a situation tha force is not applied at the first, and forces are applied after the simulation started.

But when the wire is engaged to the brackets of the teeth, forces are appied from the first which means wire is deformed already before the simulation starts.

Any idea about wire engageing in crowded teeth? I think it would be possible if i could simulate that wire passes through the holes of walls that is not located on the straight line.

Thanks

I want to find out the volume of material remove by wire edm process for that i have to find out crater radius and depth.

If file will extract in stl file format than i can easily measure the radius and depth in solidwork.

please suggest me what i have to do.

If any other method which is accurate and precise than please let me know.

Greetings to all of you

My question is first, what is the difference between solidworks simulation flow ,ployflow, cfx,cfd and fluent?

And secondly, when a researcher chooses between them. Thirdly, what is the importance of each of them, and what are the results of comparison between them and the experiments?

And finally, what is the advice given to users of these applications as specialists?

Thanks in advance

My greetings

I am a mechanical engineering student. I need a project on design using solidworks and analysis using anysis. Please share some basic solidworks and ansys project with me. I will try to do. Thank you.

AutoCad and Solid Works are two of the most famous CAD software for Engineering Design.

I am new to Ansys kindly guide me on how can I start the modeling process. I have created a solid model in Solidworks.

I used Boolean (Subtract) operation to convert multiple bodies and parts into 1part, 1body. But after this conversion, the volume and surface area become zero. Please suggest, how to solve this problem?

I have a big assembly in SolidWorks environement and my task is to minimize the overall number of bolts-connectors of it. I dont know if there is way through an analysis or anything.

Does anyone have any idea or experience about this problem?

Thank you.

Dear all;

I searched for a 3d cad software for the purpose of designing the plant of the conclusion project, and I found plenty of them, such as; Autocad plant 3d, Solid work, Factory design suite, Plant design suite, and solid edge. Although of all of those softwares, I don't know what is the suitable one?

Hello people,

I have an assembly, where i have performed a steady stress analysis.

My goal is to remove material at low stress areas in order to reduce the overall weight of the assembly.

I would like to ask you if there is a specific study at SolidWorks to reduce weight with the way i described above.

I would like a reduced material result, just like the picture i attached.

Thank you

I would like to learn drawing or getting centerline of a surface in Solidworks. I search on internet but I found limited information. I found a programs like VMTKLab.There is a section for centerline computing.

Ex: http://www.vmtk.org/index.html - computing centerlines.

Probably there is a method to get by using Solidworks.I will work on 3D modelled human leg, I want to get centerline of it to use in analysis as reference. Any ideas? Thanks.

I ask a question concerning the robots which have active and passive links -the parameter dh

does not result in direct geometry

is that there is another method which results from the geometry

one apart from geometric methods (solidworks, vr ... ect)

I want to observe particle deposition at different locations of human airway. How to use PIV and what type of experimental set up will be better?

I am trying to do a motion study. I have a path, and I want to roll the circle on that path. The path consists of multiple lines. I have saved both path and circle as block and imported them in assembly. The problem is that I can define the relation of the circle with any one of the line segment only.

   Is there a way to convert this path to the single entity to define rolling relation with the circle?

Or is there any other way of doing it?

Specifically, I have a chimney that is emitting smoke and nearby is an inlet duct that is drawing air for cooling a certain device. I need to know the percentage of smoke (contaminated air) that is drawn into the duct.

Does any one have any kind idea how to define a BC of negative pressure (suction) in SolidWorks Flow Simulation?

The software doesn't allow entering any negative values for pressure, so I am wondering how can I simulate suction.

Thank you in advance for your time.

Cool analysis using Solidworks Plastics is giving the exact same result of a cooling time of 4.09s for any analysis I conduct. What could be the problem?

I've a question regarding the SimMechanics links module. I installed the link module of SimMechanics for Matlab 2017b successfully. Then I registered and linked the SimMechanics Link software as SolidWorks add-in. Now I have a model (the robot example model) in Solidworks which I want to export to SimMechanics. So I go to the add-in tool and press Export --> SimMechanics Generation.

My Solidworks have Simscape Multibody but only have Simscape Multibody!!!

Thanks so much. I am looking forward your answer.

Allow me first to apologize in advance for the long post. I have tried to keep it right-to-the-point as possible!.

Objective

To simulate suspension of solid particles using CAD software/create a medium with a concentration of suspended particles in the air.

However, I would like to give everyone a heads up; I am of little to no experience with anything pertaining to CAD softwares - though I have started reading about and experimenting with it end of last year - and this marks my first attempt to include it in my ongoing research 🙏🏻

A chamber of a particular shape – such as cubical, cylindrical or spherical… etc.

The shape is projected to have an air inlet (an opening connected to a fan) to blow a certain quantity (e.g., in kg) of solid particles (mixtures of diameters, if possible) positioned at the bottom of the chamber prior to investigation.

Is it possible to..

Ansys 2020 R2 (student version) and Solidworks 2018 (with flow simulation add-in).

I have taken the liberty of exploring various sources to get a hold of some drawing and simulation basics using the aforementioned CAD tools in addition to familiarizing myself with some terminologies.

However, I found myself drawn to solidworks more than any other program due to its simplicity and user-friendly GUI. Using solidworks and its flow simulation add-in, I have managed to draw basic shapes (such as a cylinder with an inlet pipe) and conducted some air flow simulations, but without validations.

Unfortunately, that’s the maximum I can achieve within a reasonable time and any further attempts to figure out the meaning/inclusions of additional parameters maybe time consuming. Therefore, I would appreciate any comments/feedbacks/guidance that could steer me in the right direction.

Looking forward to your kind replies :)

Stay safe 🙏🏻

Hi all,

I have 2 .stl files which are 2 organs of the inner ear. They are segmented from CT slices and exported separately as 2 .stl files.

Some parts of the 2 organs should be contacted physically and they should share the same surface in the following Finite element modeling. However, they are 2 separate stl files, and the 2 surfaces are crossing with each other at the boundary. Is there any way to merge them together with suitable software and method to let them share the same surface at the desired part?

The sketch is attached. The stl files are 3D surfaces, and the sketch is the cut plane of the model to illustrate our problems. Thank you very much.

Please see the mesh files below if it could make the question clear. Thanks a lot!

I am interested in performing FEA on solidworks, however I am no proper knowledge of this subject. So how am I suppose to learn FEA so that I can perform it on a software

Hi,

I have imported model from solidworks and glued all the volumes.

while meshing i got warning that i have attached.

I am trying to move the circular heat source along z-axis from one end

to other, for that i have changed the coordinate system from cartesian

to cylindrical, so that i can select all the nodes in a circle.

Problem :

Instead it is selecting nodes lying inside the cirle, it is selecting

along the entire axis

I am getting different results for the same problem, using ANSYs and Solid Work Finite Element calculations, in the vibration modes package. The problem is a vibrating sphere in the quadrupole mode, using the same characteristics and dimensions, the final result is different by one percent. Is that normal? Some of these programs is more recomended for this problem?

Thank!

I want to do mandibular stress analysis and have worked on simulations for Solidworks. but some researchers have advised me to use Ansys as it is dedicated to simulation.

For my graduation project I am working with FEM analysis of bone. I have seen and read a lot of threads regarding this problem, but not yet found a proper solution. I have a stack of 2D images from a CT scan which I need to convert to a 3D model. Since this model is used for mechanical analysis, and not printing or visualization, I also need to obtain nodal density values for modulus calculation.

A similar question is asked here: https://www.researchgate.net/post/Converting_CT_scan_images_into_volume_mesh2

but it doesn't seem to present a conclusive solution.

I need a non-binary representation of each voxel, for representing material parameters.

I am running the FEM analysis in Abaqus

I have looked into Fiji and 3D slicer, but they don't seem to provide the tools I need.

I also have access to Matlab, Siemens Nx and Solidworks, if anyone should have any experience here.

This process has previously been performed at my institute using Mimics from Materialize, but that software is no longer available to me. And also, I'm going to do this job multiple times, so it wouldn't be feasible to have someone with a license to do it for me...

Is there anyone who have done this before and could share their experience?

Thanks!

Hi, 

I am trying to model two blocks on top of each other in Abaqus. The bottom block is fixed. There is friction between the blocks. Besides the gravity, both blocks are under equal distributed load from one of their sides. You can see the attached picture of the problem description ( or the link here : http://postimg.org/image/udp83oczv/ ) 

I am wondering what type of boundary conditions and interaction should I define to simulate the problem properly?

Thank you so much for the help

I am actually working on a robot.

I have some issues simulating the arm of the robot. We are actually using shape memory wire to actuate the arm made of soft material like PDMS or ecoflex. And the SMA wire is inserted in the soft material and when the wire contracts and expands the arm moves.

I am trying to simulate this phenomenon in solidworks, but the sma wire comes out and moves and pdms material remains in the same place.

Can any please help, how to solve this issue?

Looking forward to hearing.

Thank you

Hi!

I have this model (shown in the photo), but as I generated it in another software (3-matic) and I exported it as a STL file into Abaqus. I later performed Mesh to Geometry and I was left with this model.

However, I want to apply loads in the inner surface (shown with the red arrow) but I cannot select it because the program doesn't recognise it as a surface. I tried generating an instance but still I cannot select the inner surface.

I also have the inner model as well, so I was also thinking on subtracting that from this one so that I am left with what I need. I do not know how to do this as well, I tried on SolidWorks but it does not read the model.

Any tips on how to solve this? Anything will do!!

Thanks so much!
