Hello everyone!

I'm here to ask a general question concerning openFoam. Is the rigidBodyLibrary compatible with the solver overPimpleDyMFoam?

I was thinking so but now I'm stuck with my simulation receiving the following error message:

Could not find rho:rho in database
From void Foam::functionObjects::forces::initialise()
in file forces/forces.C at line 178

I went already through a lot of hours of debugging, but I'm not capable to spot the bug and that's why I'm questioning myself on the compatibility between the library and the solver.

I am fully available to share whatever relevant dictionaries, if needed.

If anyone knows, please help! I'm stuck on a very dead point.
Many thanks in advance!!

Hi,

The problem seems to be related to the definition of density. You should indicate that you are in an incompressible case by adding

rho    rhoInf;

to your rigidBodyMotionCoeffs dictionary

Thank you for your reply gcampana.

Basing myself on some previous threads, I already tried what you suggest me to do. Unluckily, it doesn't work. By the way, I've slightly changed the approach so it is not an urgent stuff.
