Combining Object Files

[jdmay]

I am using the Abaqus adjustable rigid torus addin to model balloon angioplasty in stenting procedures. The artery is already compiled to an object file (.obj). I will also need to use a uhyper subroutine to model the artery's hyperelastic behavior. I have written the subroutine. I know that Abaqus requres that there only be one subroutine file. How can I use my subroutine in conjunction with the pre-compiled addin? Is there a method to link the two files?

Yes, you can link two (or more) object files into a shared library file that Abaqus can use. It is not that hard once you have the necessary compilers, etc installed.

Thanks for the reply. I link the files using the Abaqus command prompt, correct?

I've tried to use the abaqus make library command to link the two object files into a shared library. However, abaqus isn't able to use both subroutines in the analysis. Could I be doing this incorrectly?

You have 2 choices:

(1) combine your 2 sources files into one file and then have Abaqus compile it for you.

(2) manually link the two object files into a shared library file. I often use this approach when creating shared user-material files, but it requires some compiler expertise to get it right

I was able to get both ways to work. Thanks for the help.
