Hi there,

I would genuinely appreciate it if you could help me on this issue:

I am going to solve an FSI problem with a modified version of rigidBodyDynamics library. To start, I just copied its directory somewhere:

 
cp -r  $FOAM_SRC/rigidBodyDynamics $FOAM_RUN/MyrigidBodyDynamics

and changed the last line of the Make/files to:

LIB = $(FOAM_USER_LIBBIN)/libMyrigidBodyMeshMotion

Then using wmake I complied this new(!) library into $(FOAM_USER_LIBBIN) directory.

Now the question is how I can use this new library in my cases. When I set the constant/dynamicMeshDict as

 
dynamicFvMesh        dynamicMotionSolverFvMesh;
motionSolverLibs    ("path_to_the_lib/libMyrigidBodyDynamics.so");
motionSolver             rigidBodyMotion;
...

the OpenFoam can seemingly find my new motionSolverLibs but it has some problems with motionSolver as it complains:

 
--> FOAM FATAL IO ERROR: (openfoam-2112)
Unknown solver type rigidBodyMotion

Valid solver types :
6(coded displacementInterpolation displacementLayeredMotion multiSolidBodyMotionSolver solidBody velocityDisplacement)

Is there any way to make it use the new library?

I must be missing something here, you want to load rigidBodyMotion from librigidBodyMeshMotion automatically required through your libMyrigidBodyDynamics ?
Did you actually add that as compile option somewhere (eg, LIB_LIBS) and it didn't work, or something else? Really confused here.

Are yoou sure, that you used the correct libname? Because you have written you renamed the library to "libMyrigidBodyMeshMotion" but you are loading "libMyrigidBodyDynamics" ??


If this isnt the case I would try $(FOAM_USER_LIBBIN)/libMyrigidBodyMeshMotion.so


But these are just guesses, never worked with that before

Thank you for your reply.
You are right! I had forgotten to compile libMyrigidBodyDynamics.so. Thus both the situation and my question were confusing. After getting the comments, I figured out what the problem was. Thanks.

Thank you. The issue you pointed out was not exactly the problem, but it was very constructive.
