I have used OpenFOAM and Calculix to achieve coupled computation through precompic data exchange, and currently it can also perform long-term calculations normally. But I did not add boundary layer mesh to the solid wall in the fluid solver. When I add a boundary layer mesh, the original calculation will report an error message indicating “floating point overflow” in the OpenFOAM solver, which is likely caused by negative volume in the boundary layer mesh.
I noticed that none of the coupling cases between OpenFOAM and Calculix in the Precice tutorial cases added boundary layer meshes. I would like to know if the coupling of OpenFOAM and Calculix supports adding boundary layer meshes to solid surfaces in OpenFOAM, especially for cylinders with aspect ratios of over 100
