[fish man]

Hi everybody,

I am creating a motion to create the movement of a fish. The motion is called "swingUndulation2". I used the polymerized lattice method. I adjusted the mesh and boundary conditions and ran the analysis on one core and got the following error message.

#0 Foam::error:rintStack(Foam::Ostream&) at ??:?

I don't know if it's a motion problem or a mesh problem...I get 11 errors, but I don't know what's important.
If anyone knows, I would appreciate it if you could help me.
Thank you in advance.
