LSDYNA: User define subroutine for friction interface
LSDYNA: User define subroutine for friction interface
(OP)
Hi all,
How do I set up the user def subroutine for friction interface?
I already have the *k file that uses the subroutine.
I also have the fortran file (*.f) file already. How do I execute the k file?
I cannot find any commands in the *k file calling the subroutine file.
there is no *include or anything that I see is linking the *k file to the fortran file.
I do not understand the steps actually. What are the steps involved to run the *k file using user defined subroutine friction interface?
Any suggestions would be appreciated very much.
Thanks.

I am sorry I acted like an expert, which I am not actually. I never used LS-DYNA, but has messed with some other popular FEAs on their user subroutines. So I just shared my similar experiences.
Basically the only way is to read their manuals; if no success, contact their tech support. You need to know how they designed the ports for subroutine and what variables are available for your subroutine, etc. You have to let them tell you that, otherwise, you can't figure it out by yourself.
One time, I tried to use one subroutine function they claim they have in manual, but very generally and couldn't; then I contacted their tech and found out the function won't be available until next release. That was really a shame, because I simply had to wait .5 year for the function to come out.
Sorry again, can not answer your questions.
