Dear researchers,
I'm looking for an open-source FEM software compatible with ABAQUS subroutines. I know there are a few open-sources FEM software available. But the question is; Is there any open-source FEM compatible with ABAQUS routines? or can be compatible with minor changes in the code?
To conduct my simulation, I need to run a few routines but they are ABAQUS subroutines and are written in FORTRAN and I don't have access to ABAQUS license for now. I know that ABAQUS has a student version, but this version has limitations among which is a restriction on running routines.
Any comments and pieces of advice are highly appreciated.
Best,
Farhad
Hi Farhad,
You could try Calculix. I've used it for running ABAQUS-like input files, although I haven't tried out its user subroutine interface.

Let me know how you get along - I am curious :)

Hi Milan,
Thank you for your comment. There is only one problem, the software is based on Windows O.S. and I run Linux. I am going to see if I can run it with PlayOn Linux or Wine.
Any other suggestion?

No, sorry mate. That's the only program I know of. But I haven't looked for such a program in a few years, so there may be others by now.
Best,
Milan.
Hi Farhad,
So it turns out I was wrong earlier. Calculix is available on Linux:

Have fun, and do let me know how it turns out!

Hi Milan,
Thanks for the link. I will give it a try to see how it goes. I will let you know.

Hello, I would like to know if you succeed in using abaqus subroutines with calculix. If yes, what was the procedure to follow?
Hi Alann,
At that time, I got access to a cluster with Abaqus on it, so I didn't get the chance to play with calculix.
Farhad
Hello Farhad,
Thank you for your answer! Then I will try to find the way to make it work.

Alann,
Please keep me updated about this. As soon as I make some free time, I will give it a try again.

I have not tried this myself, so might just be an endless chase for the Hole Grale. But the Calculix Manual claims that there are ways to include ABAQUS umat routines at least. See more at: http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node278.html
From what I read so far one needs to recompile a calculix executable file that include the umat subroutines. It doesn't seem to be complicated when reading the procedure given on calculix website but in practice it is a bit different.
I am giving ABAQUS Subroutine/UMAT Lectures here:

future lectures will come later this year
Hi Ronald,
Thank you for your input. I became aware of your lectures yesterday through Linkedin and it seems like a pretty amazing package you have prepared.
