How to do ABAQUS Scripting; Simulating a Simple Disk Compression Test

[@issarraf]

Perfect, informative and comprehensive! Good job! It is really useful! well done!

[@ShubhamSahu-vj9mf]

sir, is there any help in creating the functionally graded material part and analysis

[@emrankarimi9887]

hi . how can i create several cylinder in solid object?

[@chaitanyasurepally8249]

Thank you for the information on the abaqus python scripting..

[@Highoctane35]

Awesome video you have made. I have a question. How do you create and view the jnl. file? I can't create this.

[@ArashJENAB]

Hi, the jnl file is created by ABAQUS automatically. If you don't see it in the temp folder (c:\temp by default), save your newly made model in a folder and jnl files will be saved there too.

[@arjunbalasubramanian3308]

Thank you so much sir. You have explained it very well.

[@shafiq2450]

Thank you so much Sir, for the video. It really helps me a lot. I want to ask if you have any resources for the multi-scale modelling of concrete samples (cement paste+aggregates+any type of filler) as it needs some steps for homogenization. Thank you. Have a great day ahead!

[@jayeshkhajwania376]

Please upload some tutorials on python scripting for hypeworks.

[@taarigo6119]

Hi Arash, Thanks for this video, it's awesome. I've tried to set up and run the same script, but I'm having this error at the job line: Unable to start an analysis job. Please do you have any clue of this issue? Thanks

[@offshor]

What is the name of jnl file editor? The colors are beautiful.

[@antejurcevic5855]

I think it's called atom

[@sjz5339]

sublime txt

[@ehsankk1636]

thanks a lot sir.

[@ArashJENAB]

Most welcome

[@KrishnaKumar-sh6qu]

From where did you put the Johnson Cook Parameters?

[@ArashJENAB]

Hi Krishna, Same reply, sorry! from the main account! The constants were calculated for AA5182-O which was a part of my PhD research. Please find the following DOI for the paper: doi.org/10.1016/j.matdes.2016.01.038

[@KrishnaKumar-sh6qu]

I have to calculate the triaxiality ratio for flat plate specimen for Johnson-cook material model.Can you tell me any research paper on flat specimen?

[@lyhourchhay2981]

Excuse me ! what package do you install in sublime for *jnl file ? I try to install abaqus sublime package but doesn't have color on the keyword as yours

[@sjz5339]

lower right corner choose python language

[@imdadimmu8741]

Thanks sir 😁

[@thananjayansivaprakasam2175]

Thanks a lot. It was much useful.

[@antejurcevic5855]

Dear Arash, Thank you very much for your tutorial, it has been of great help to me. Since you know a lot about abaqus scripting I would like to ask you for some help. I'm trying to write script that will generate a model and define node sets on the right and left edge of my specimen. However, when I change the mesh the script isn't working correcty, that is the node sets are not defined correctly. Do you know how could I be able to write script that will define node sets correctly, regardless of mesh?

[@wahaajali1009]

When you find solution please let me know also.. I am trying to do a similar thing

[@antejurcevic5855]

@@wahaajali1009 Hey Wahaaj, The solution is this: You have to use "bounding box method" in order to select nodes that you want. You will need to define coordinates of the bounding box and than abaqus will pick them and make set of nodes. See these two links: dsk.ippt.pan.pl/docs/abaqus/v6.13/books/ker/default.htm?startat=pt01ch31pyo06.html and imechanica.org/node/11449 Good luck !

[@ArashJENAB]

@@antejurcevic5855 Thanks! I didn't know this and will look it up. What I used to do was to set up an array of mesh sizes and node numbers for all the area I was interested and run a script to export data I wanted from those node numbers (which were again dependent on my mesh size).

[@hsoley]

Amazing, thank you so much!

[@arnauldroberttapa2139]

Thanks. Can you please tell me what are the computer system requirements to use abaqus script with python especially with the objectif to link abaqus with matlab. Actually I have noticed that there a couple of command windows that I cannot open like JnI.. I am actually very new in all these software but I hope I could achieve my goals with your advices.

[@arashj666666]

I think any system that can handle Abaqus should be fine... .jnl files are simple text files, you can open them with any decent text editors like Notepad++ or Sublime...

[@wahaajali1009]

Thanks

[@ahadnoor2358]

can you upload some thing related dload subroutine

[@Nguyennhunam1]

Thanks for the video. What is the editor you used to open jnl file? I used Notepad ++. It did not show different command as shown in video.

[@ArashJENAB]

I use Sublime 3 because I like its themes and capabilities much more. But in general, jnl files are Python files; so if you want to see the commands and etc., you need to enable Python syntax for .jnl files as default.

ERROR: THE MEMORY ALLOCATED TO PROCESS CONSTRAINT IS NOT ADEQUATE. SET THE ENVIRONMENT VARIABLE ABA_SCALE_STD_CONTAC­T_CONNECTIVITY TO A VALUE OF 1. AND RERUN THE ANALYSIS. I need answers please

[@venkatseshank9454]

HïI am currenty working on tensile test of LDPE in abaqus where, i should make the parametric study of youngs modulus in single point optimizaton in matlab.Can you help me with that

[@fofoMohammed-qk3qz]

Hi Aarsh I used abaqus with matlab to do optimization.I executed the python script of abaqus from matlab by using the command “abaqus cae noGUI =my script .py” The process of the optimization in my work is done by matlab by using a Genetic algorithm function. Which changes the parameters in the python script, runs it and compares the results .So this process will repeat itself to get optimum results and this lead to run the abaqus per each stage of optimization. My wondering is there any way to keep the abaqus cae opening without closing when the job finished, to reduce the time in my work

[@arashj666666]

Thanks, I think it is, please email me if you still have this question 😊

[@fofoMohammed-qk3qz]

Hi Arash Yes , I still have this question i do not know your email

[@fofoMohammed-qk3qz]

please ,this my Email: [e-mail]

[@azzia1322]

well done! do you use abaqus with user-subroutine ( UEL fortran) ?

[@ArashJENAB]

Hi Azzi, I have coded my material response in VUMAT (free format Fortran). But, you can always code UHARD or similar subroutines for your material :) Bests, Arash

[@miladbd8029]

It was really helpful! Sepas!

[@mahdisaadi8190]

Thank you so much

[@87backkick]

what text editor are you using?

[@ArashJENAB]

+Colter Roskos I use Sublime, which is the best text editor I've found so far :)

[@87backkick]

thanks for the quick response. I cam across Notepad++ which seems to work pretty well.

[@offshor]

I was about to ask this question :) Sublime. Thanks!

[@BonliRd]

Hi, do u know any source which shows how to execute UHARD subroutine? I need it to my study project.

[@ArashJENAB]

+BonliRd Unfortunately, I have never worked with UHARD but you probably can find some useful tutorials online... ABAQUS help also can give you some ideas...

[@BonliRd]

I just went in friday to my promoter worker and he helped me out. Any way, thanks for response.
