I keep receiving the infamous sigFPE error (see below) and I cannot get this case to run for the life of me. I have a list of points defining a foil shape, which I am going to animate following the Chalmers myWaveDisplacement "Make A Fish Swim" using pimpleFoam. I took the list of points, made a 2D STL shape, extruded it in paraview, and saved the resulting "3D" shape. I am trying to use blockMesh to make a box around the shape, and then snappyHexMesh to get the shape into openfoam. Case files are below and picture of STL file is attached (it was too big to attach the actual STL file). Can anyone help me with this? I think it is an error with my p boundary conditions based on when it crashes but maybe not.

*if it matters, I am running Openfoam8 on my Mac

Hi, I am also focusing on this part, did you solve the problem?
