Does anyone know how to solve AbaqusExecutionError('Abaqus/Explicit Packager', -1073741511) , there are no any .sta or .msg files generated .for, .inp and .dat files are fine. [*1] I can easily run all subroutines listed in https://lnkd.in/dMqZNyCm [*2] Abaqus verification shows pass on user subroutine with standard and explicit. Abaqus2020 vs2022 inteloneapi 2023 [*3]

Hi everyone

I have a tooling simulation .sta file format which looks like it is Abaqus file format. I don't know with which software it has been made but it contains object's mesh coordinates.

Now I want to use it with ANSYS and even conevrt it to more conventional formats like STEP.

Can anyone help me in this regard?

Thanks

I am using NetSim 802.11 n / ac library and wanted to know how to vary CW Min and CW Max. More specifically, how do I

make (i) a global CW change that affects all APs/STAs (ii) a local CW change that affects only some APs/STAs

I want to stain some bouine fixed paraffin embedded mouse brains from more than 30 years ago for Nissl (Cresyl Violet) staining, but should remove Picric Acid first (there was no staining at all). I found in re-hydration steps, I should use 70% EtOH with Lithium Carbonate (saturated), does anyone know how much lithium carbonate should I add to how much 70% EtOH? And for how long I should keep my tissue in 70% EtOH+Lithium Carbonate?

Any other effective methods for removing Picric Acid?

I would like to know if there is any seismological processing of local data by python. (MSEED format)

The black curve corresponds to the DTA analysis and the blue curve for the TG analysis. Regarding my previous calculations and the melting temperature of the elements of this alloy, I can guess that the peak available at a temperature of 1080 degree Celsius is the melting point of the high entropy alloy. Is there any person who can guide me about the present peak in the temperature range of 600-800 degree Celsius ?Which analysis, references and papers can i use to more information?

I was working on thermogravimetric analysis for some materials, however, because of the pandmy I stoped using the STA TG DTA-DSC 1600 for like 6 months, when I was able to work again with it, the temperature measurement system seems not to be working, now when I connect the software with the analyzer the frunance sensor marks 1740°C all the time, even without heating and the external sensor marks 0°C. Can somebody tell me what the problem might be or any sugestion on how solving it?

Thanks in advance.

Hello everyone,

I'm doing a sheet metal forming simulation on Abaqus and it's my first time working on this software. After submitting the job on Abaqus several times via command prompt and CAE, the job is never completed. In the .sta file it just stops running and it doesn't show errors. The maximum ODB Field Frame Number of all my submitting attempts was 11 of 20 requested intervals, which is not enough.

Does anyone know what could be the reason? I'd be very thankful for any advice.

The question is what remains in the urban planning and in our professional and intellectual experiences of Giuseppe Campos Venuti and Federico Oliva? What about discipline now?

They reasoned and worked together, they proposed urban plans and organized technical offices, and now they are gone, but their legacy lies in the contributions they have spread throughout plans, conferences, magazines and books.

Campos Venuti and Oliva worked on planning, believing in social services, ecology, infrastructures as tools to build towns without suburbs, towns made up of centralities. Those who, therefore, have found in their words and actions the stimulus and strength to operate as planners and to engage in politics with the conviction of being able to make a contribution to freedom, equality and brotherhood in the territory, are the witnesses aware of their thinking.

La domanda è cosa resta nell'urbanistica e nelle nostre esperienze professionali e intellettuali di Giuseppe Campos Venuti e Federico Oliva? E la disciplina adesso?

Hanno ragionato e lavorato insieme, hanno proposto piani urbanistici e organizzato uffici tecnici, e ora non ci sono più, ma la loro eredità sta nei contributi che hanno diffuso attraverso piani, conferenze, riviste e libri.

Campos Venuti e Oliva hanno lavorato sulla pianificazione, credendo nei servizi sociali, nell'ecologia, nelle infrastrutture come strumenti per costruire città senza periferia, città fatte di centralità. Coloro che, dunque, hanno trovato nelle loro parole e nelle loro azioni lo stimolo e la forza per operare come urbanisti e per impegnarsi in politica con la convinzione di poter dare un contributo alla libertà, all'uguaglianza e alla fratellanza sul territorio, sono i testimoni consapevoli del loro pensiero.

Hi,

I am trying to use the ABAQUS/standard solver to simulate the single crystal deformation behaviour with DAMASK framework. The materials is BCC ferrite with hooke elasticity and phenopowerlaw plasticity. The model is a 2D cube with a mesh element type CPE8. Boundary condition: left U1 constrained,, bottom U2 constrained, and top with minus V2.

The job ran without errors, but there are many 'position not found when parsing line' warning in the .dat file and 'THE SYSTEM MATRIX HAS xxx NEGATIVE EIGENVALUES. ' in the .msg files. What is the question?

I am new to DAMASK and have insufficient experience. Any suggestion would be greatly appreciated.

Attached are the INP, MSG, DAT and STA files.

Thanks.

Hello there,

We have found CO2-Peaks on different aged clay ceramics by STA/DTA-FTIR analysis at approx. 300-400°C and 500-600°C. We found no Carbonates with the XRD. Does anyone have an idea here?

I’m trying to evaluate the thermal behavior of geopolymers in the range of 25 – 1000 °C by means of a LINSEIS STA PT 1600 - Simultaneous Thermal Analysis (TGA+DSC), which use the default software (Tawin L81PT type S). However, the data evaluation module provides the peaks areas values in µVs/mg. Is there any way to convert these values in mW/mg?

I have a a simulation using mininet-wifi where I want to measure loss, delay and bandwidth of the stations at different distances and received transmission power from associated APs but unfortunately the powers of the AP received to the STAs do not change and I dont know how do I get loss and delays

Dear community,

I have a simple (but quite heavy) 3D Abaqus/Standard Model implemented with a UMAT that stops converging when 80% of the step is completed (please refer to the .sta and .msg files). The model loads a short beam in three point bending. I have tried both Newton-Rapson and Quasi-Newton methods with faster performance in the latter. Would you kindly have any suggestion to improve the convergence performance?

Thank you in advance for your help

Dear all,

We want to model a pressure vessel using WCM (Wound Composite Modeler). We have built a model  by following  the instructions in user manual and examples. For post processing, UVARM subroutine was generated by WCM Plug-in. Then we have run our input file with UVARM subroutine; however, we have encountered an error as expressed below;

" Abaqus Error: The executable Standard with system error aborted with system error "illegal memory reference". (signal 11). please check the .dat, .msg, and .sta files for error messages if the files exist." 

Since we have no internet connection at our computer where input files are run, we can not generate system information to report. When we search the error on the internet, common offer for solving problem is avoiding parallelization but we have tried it with one cpu and we have encountered with same problem again. 

By the way, to compile and run our model, we made some changes in UVARM subroutine file. It is that logical definitions were changed into integer definitions (e.g. false->0 and true->1) because we use gfortran as compiler.

Could you please inform us about the possible solutions to our problem? We're looking forward to your reply. Thank you in advance.

Biolegend Cell Surface Immunofluorescence Staining Protocol uses 15 ml of cell staing buffer to resuspend the cell. Is it necessary? Here is the link: https://www.biolegend.com/protocols/cell-surface-immunofluorescence-staining-protocol/4283/

I am doing O2/CO2 research on Combustion and for that I recently need to run some tests on TGA machine model STA 449-F3. My query concerns the selection of Purge gas 1 on the software. This TGA allows me to select different gases only on Purge 1 while Purge 2 is fixed for a very few options. In my case, I have to use a mix of Oxygen and CO2. I have used 2 controller and a flow meters to mix the the gases in the required composition and then attaching to the input of Purge 1.

Now, my question is, does the selection of a Purge gas 1 on the software, has any effect on my results, where if the input mix remains the same?

like if I choose Oxygen as P1 on the software and input mix in actuality is 30% O2/CO2?

Secondly if I choose a previously defined selection option, in the software, of 30% O2/CO2 having density of 1.82 (as shown by the software) and still the input is the same as before, 30% O2/CO2, will the software change the results depending upon which P1 I have selected?

Are the results in this particular TGA, as per received cases?

Does any of the above assumptions and changes have effect on FTIR results?

Hello all,

I am using FRIC Subroutine and I get the following Error. Anyone has an idea about that?

I changed the file name "mkl_avx2.dll" into " mkl_avx2.dll.11.0.0.1". But it does not still working. Moreover, it is not related to the compiler and so on because it works for the other subroutine codes properly.

Many thanks for your comments.

Hello, i'm trying to implement the Paris law in Abaqus. My model consist in a clamped-clamped beam loaded in the middle by a concentrated force. In order to simulate the crack propagation I create an initial crack and i want to propagate the crack trough XFEM and with a low cycle fatigue analysis (direct cyclic). I implement the Paris law in the keyword editor but when i run the model i get these errors at the end of the first cycle:

La simulazione nella formazione del personale medico, paramedico ed in genere delle figure che operano a contatto con i pazienti sta acquisendo un ruolo sempre maggiore nella formazione medica, sotto la spinta della maggiore disponibilità di strumenti e ambienti sempre più realistici supportate delle più moderne tecnologie e dell’identificazione di metodi efficaci per il loro uso. Non vi è disciplina o livello della formazione medica universitaria o post-universitaria che non possa trarre giovamento dall’uso delle più moderni strumenti di simulazione, a patto che siano scelte in base a specifici bisogni e non per il gusto della tecnologia. Purtroppo nel nostro paese manca una vera e propria cultura nell’utilizzo di tali strumenti per cui l’introduzione di queste attività dovrebbe essere promossa fino dai primi stadi della formazione medica. La complessità della pratica chirurgica possono ad esempio rappresentare un’ardua sfida per i progetti di formazione e training medico scientifico; le simulazioni interattive ed immersive di fatto accelerano il processo di apprendimento, innovando i modelli di formazione sino ad oggi definiti come tradizionali. Oggi più che mai si sente sempre più parlare di realtà virtuale che applicata alla medicina è in grado di consentire il trasferimento di know-how tra un medico ed il suo allievo, offrendo un elevato grado d’interazione più immediato. La realtà virtuale di fatto rappresenta l’ultima frontiera dei nuovi media, permette di elevare la comunicazione a un livello esperienziale, trasformando l’osservatore nel protagonista della scena. Questa tecnologia si sta facendo varco come applicazione e metodologia pratica in tutti quei contesti in cui l’immedesimazione, il realismo e l’immersione dell’utilizzatore nell’ambiente virtuale rappresenta un valore aggiunto poiché capace di fornire stimoli molto simili a quelli naturali definiti dalla realtà. Stimoli ai quali il medico apprendista tenderà a rispondere parimenti in maniera “naturale”. Tutto ciò rende questa tecnologia lo strumento più potente messo a disposizione per tutto quello che riguarda la simulazione della realtà e la formazione esperienziale specialistica, in cui l’esperienza e pratica devono integrarsi con la parte teorica. I moderni visori indossabili consentono oggi di realizzare prodotti audiovisivi con un livello di realismo senza precedenti, capaci di immergerci al punto da ingannare i nostri stessi sensi. L’integrazione con i sistemi di motion capture, amplificano il senso di presenza durante l’apprendimento, permettendo di interagire con l’ambiente virtuale in modalità naturale e intuitiva. E’ proprio per queste ragioni la realtà virtuale ha come campi applicativi la formazione e la simulazione in campo medico. Inoltre rappresenta uno strumento con grandissime potenzialità per tutto quello che concerne la valutazione di prototipi di protesi e la loro simulazione di ambienti e scenari artificiali. Trasponendo in realtà virtuale modelli e progetti, non solo il medico, quanto il paziente stesso potranno avere una chiara percezione della loro caratteristiche di forma, del loro funzionamento e della loro contestualizzazione in scenari di vita quotidiani come se fossero stati realmente e fisicamente realizzati. A livello mondiale in campo medico la realtà virtuale è ancora in corso di sperimentazione essenzialmente con le applicazioni di training on the job e la cura dei disturbi di ansia e delle fobie. Nel primo caso tipicamente si adopera una telecamera 3D installata in sala operatoria e/o sul medico che sta operando per consentire ad altri di assistere in maniera immersiva all’intervento stesso. Nel secondo, si sfrutta invece il realismo offerto dalla realtà virtuale per ricreare alla presenza di un medico situazioni e scenari capaci d’innescare fobie, attacchi d’ansia, o patologie più gravi quale ad esempio l’autismo, al fine di poter essere meglio interpretate le azioni da intraprendere. La realtà virtuale permetterà ad ogni studente di avventurarsi nell’attività da apprendere, senza una partecipazione distaccata ma pienamente immersiva nel ruolo che dovrà ricoprire. Non si parla solo di visori, infatti, ma di ulteriori dispositivi come guanti speciali che offriranno stimoli tattili permettendo di apprezzare la concretezza dell’intervento, il contatto con un corpo e tutto l’impegno richiesto. Nel prossimo futuro l’economicità del sistema renderà inoltre possibile trasmettere queste esperienze in streaming a migliaia di utenti dovunque nel mondo. Un’opportunità di equità ed omogeneità per la formazione dei professionisti sanitari di tutto il mondo. L’obiettivo del prossimo futuro sarà quello di sviluppare progetti a supporto dell’acquisizione e trasferimento della conoscenza capace di realizzare esperienze fuori dal comune, con un approccio pragmatico ed efficacie. Intellisystem Technologies intende partecipare attivamente alla definizione di nuovi metodi e strumenti per valorizzare queste tecnologie avvalendosi del prezioso supporto e collaborazione delle Università Italiane ed estere.

FNAC is an assay which has high sensitivities when optimally selected is efficient and one of the most accurate frontline method for the diagnosis of Tuberculous Lymphadenitis. It is effectively supplemented by Ziehl-Neelsen Staining which is the most simple, quicker, reliable and relatively cheap diagnostic tool .

After SNL i harvested the spinal cord segments, Using Trizol reagent i isolated RNA then Protein extraction, measured protein concentration by BCA and had a relatively good concentration. Used the protein for WB. Primary antibody was Iba1, i couldnt get any band. but i had very clear bands when i used GFAP=astrocytes.

On ther hand, after perfusion fixation with 4% PFA, harvested the spinal segment, overnight in PFA, followed by 10,15,20% sucrose. cryopreserved the sections. cut 30um sections and tried to staing Microglia, using the same Iba1, but failed.

Has anyone encountered a similer difficulty in both WB and IHC-F?

What did you do to solve the problem?

Will changing the company help?

Thank you.

I am starting to write and test VUMAT for my Abaqus simulation. Since mine is a linux system and I can't buy a licensed Intel Visual Fortran Compiler, I am using the default gfortran compiler available in linux. I tested a single material VUMAT and it got compiled. Abaqus was able to read it and use it for analysis.

The problem arises for a multi-material VUMAT. It shows no compilation errors. But when I submit it along with my Abaqus job, Abaqus gives the following error. The .msg file is not formed and the .sta file is empty. 

'Illegal memory reference' (signal 11).

The same VUMAT gets compiled and the input file gets executed when compiled using Intel Visual Fortran compiler on another system.

Please let me know any changes to be made in the gfortran compiler or if additional information is needed.

Thank you.

I have a question on how to calculate IC50 of drug treatment on cell survival.

I did three independent experiments in 96--well plates using the MTT method. After putting the OD values into Prisms one experiment at a time, I got three different IC50s. From these I got an averaged IC50. However, when you want to present the fitted survival curve, you can only choose one representative curve from the three, right?

In order to show a curve which will incorporate all data from the three independent experiments, I did the following and I want to know if this is acceptable. For experiment 1, drug concentration 1, I averaged the OD values from triplicate wells and normalized it to control (100% survival), and got about 10% survival. I did the same thing for exp. 2 & 3, calculated their survivals at this drug concentration, say 11%, 12% and similarly calculated survival for all the other drug concentrations. This way, the data input for Prism would be: Drug Conc. 1, 10%, 11%, 12%; (each is the average from one independent exp.) Drug Conc. 2: 20%, 21%, 22%, etc. Now, Prism will only return one fitted curve and one IC50 value. Is this data manipulation acceptable? Thanks!!
