How to use the spring in rigidmotion of openfoam with calculix?

I change the linearspring.c in openfoam to reach some aims, but I don’t know how to use it with calculix.

Hi @futer,

I am not sure I understand your question, and I have no idea what linearspring.c does. Could you please elaborate on what you are trying to do, what you have tried, and what has failed? Do you get any error messages?
