Questions related to Adina

You know for example, the couple between ANSYS and FLUENT is very common for Thermal-FSI simulation.

Is there any software for carrying out all process of Thermal-FSI only using one software?

Which software is easier and more user-friendly than other?

For example, I think ABAQUS is very easy and good software for Thermal-CFD simulation, however, what is easier software for Thermal-FSI simulation?

I'm a beginner, and I want to learn an example in a teaching book.

But I can't find "strain" in band plot variable.

Why?

I am trying to run a direct FSI simulation at steady state in ADINA. The flow is 3D, laminar and incompressible, while the structure is linearly elastic and incompressible. I have created the mesh. The solid part has 3663 3D solid elements, and 35903 nodes. The fluid part has 28083 3D fluid elements, with a 32256 nodes. However, the solution is not able to even start, and I get the error " No enough memory to continue".

Could you advise, how to solve this problem?

What is the best finite element modeling software packages for modeling non-linear and fracture analysis of CONCRETE? I've had some with ABAQUS standart/explicit, but I would like to learn if there is a better software for non-linear behaviour and fracture mechanics of concrete according to your experiences.

Best regards.

I need to model pullout of a yarn in concrete matrix

Which two software of ADINA and ABAQUS are better for fluid structure interaction (FSI) simulation?

I have studied the calorific value of branches as well as stem of 20 tropical tree species like Gmelina arborea, Tectona grandis, Adina cordifolia, Dalbergia latifolia, Ficus religiosa, Ficus benghalensis, Melia dubia,Albizia procera, Mitragyna parviflora, Azadirchta indica, Lagerstromea lanceolata, Saraca ashoka, Pongamia pinnata, Mangifera indica Syzygium cumini, Acacia nilotica etc. I have found that in most of the tree species the calorific value of branches are approximately same or slightly more than the stem samples in 45-60 cm girth class..

I'm studying the behavior of piles in different soil profile . when i define pore pressure .

1- the value of pore pressure When using units ( Newton , meter , second , Kilogram ) :

the value = water density * Water Height *9.81

or

the value = water density * Water Height

2- the soil density is effective or Bulk

Hello Everyone, I am also facing the problem of TI decaying very fast in my simulation of turbulent flow . I am modeling the flow around 2D square cylinder and used k-e model. I made the model in ADINA and computed the values of k and e based on TI, length scale and mean flow velocity. I don't have the option of entering the turbulent viscosity. So any suggestions on how to solve this problem?

I have this project about atherosclerosis and huge amount of computation. I don't know how can I use parallel computing in ADINA or using a cluster or distributed computation. The information in the internet is so confusing. Anyone know an introductory book?

I tried different coefficients of friction (Extrermums) and no changes occurred in results.

Good to know the target is rigid.

Some software that researchers have used in the past to carry out a FEA for pavement structure e.g. ANSYS, ADINA. It could also be a open source software developed by a research group.

Software specifically built for FEA of pavement structures like EverStressFE.

i need a pre-processing app to generate fine mesh which could be imported to ADINA AUI . i have tried FEMAP but it seems to be inappropriate for two-way FSI simulations. I want to know if there is any better method to do so.

hi every one

I have mesh file from ICEM in format of nastran. my geometry a little is complex. I have problem to chose element to set boundary condition. if some one have experience with Adina please help me.

see the attach file

best regards

There are many Finite Element softwares that are some commercial and some not. Many of them are open-source and some are closed-source. Abaqus, Ansys, LS-DYNA and ADINA are familiar to all mechanicals. I want to know what bases are needed to develop FEM software like e.g. Abaqus? What language do you suggest to programming for such softwares? What Abaqus did to be great software? Except mechanical engineers, what types of engineers are needed to develop this software? What do you suggest to start this great project? How can develop it? How can find marketing for it? How it can be user-friendly? Do you think it should be university-based or it can be developed in an independent lab? Is there any reference that explains this procedure? For example, Finite element Procedure is wrote by J. Bathe, Funder of ADINA.

Hi All,

I am trying to simulate deformation of a cell as it moves through a micro-constriction (due to fluid flow) and I was wondering which software is capable of that. I have found a group of papers (mostly from the same group) who have used ADINA Fluid-Structure-Interface to relate transit time of the cell through the constriction to its viscosity and shear modulus. This is exactly what I am looking for but ADINA is not user-friendly, so I was wondering if anyone could suggest me a more straight-forward software.

Thank you for taking the time to help me:)

I want to know if the Adina software is suitable for solving geotechnical problems (dealing with the excess pore pressure for example)?
