USER MATERIAL SUBROUTINE

Altair Forum User

Hallo everybody,

I had wrote a user subroutine with material law29. But I don't know how to start the solver with this subroutine.

The Subroutine is a *.f Fortran File. Please could anyone tell me which solver option I have to use to make the subroutine run?

Hi,

Here is a pdf that gives a clear idea of what can be done
Note that starting with v14, it will be possible to use gfortran compilers.

Hi Rahul,

thanks for the answer and the guide. Is it possible to lunch the subroutines in the fortran format directly when I call the solver? Or is the only why the DLL thing described in the file you posted?

Hi,

We do not install compiler packages with HyperWorks. There might run-time DLLs/shared libraries but we do not install whole compilers.As mentioned above the coming version will have detailed documentation for subroutines.Once it is availavle we will update you.

But when I try to lunch the solver I get this error message:

Also there are two files called SITest_0029.scr and SOTest_0029.scr. Which function these to files have?

Hi,

I solved the problem by myself. The Input Format in the engine file was incorrect. So I changed it and now everthing works fine!

Thanks for the support!
