Hello everyone,
Please, can I use olaFlow for generating waves with OpenFOAM-CalculiX coupling?
I’m using Ubuntu 20.04, OpenFOAM v2112, CalculiX v2.19, and preCICE v2.4.0.
Maybe @Stan could help here, as he has already mentioned olaFlow a few times:
Hello,
Thank you so much for your reply.
Yes, of course. preCICE is a very helpful and flexible tool, so you just need to add the appropriate settings related to wave generation.

I just try to do it but I can’t, can you help me please?
while the 3D running I had the following errors can someone help ?

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

Looking for any time directories without results (e.g. stray functionObjectProperties files, see openfoam-adapter issue #26 on GitHub)...
The present information is too limitied to figure out the possible problem. Maybe you need to upload more settings of your case for others to help you, for example, your configuration file, and settings for solid and fluid parts.
Does the uncoupled fluid simulation run normally? I am wondering why the residuals and the Courant number are perfect zeros.
