When I finish setting the boundary condition and voltage and proceed to the next step, the SPIS prompts that there is an error in meshing.
Such as “Error in UI2NUM ThreeDUnstructVolMesh.autoThinSurfaces:volume mesh surface 1386 has no neighbour cell and duplicates a surface with no neighbours!”
And sometimes when I finish modeling with gmsh and import it into spis, spis does not display the model.
Please help me. Thank you！
Hello, did this ever get sorted out? I am new to SPIS and have this same error
ME TOO！So is there any solution?
Somethings wrong with the mesh. Perhaps your mesh is of poor quality (have a look at this in gmsh, in statistics you can look at the distribution of quality (.e.g “gamma”) and even visualise where the issue are. Hopefully you can just run some optimization routines to fix most quality issues. You might need to refine the resolution at some places.
It might also be the case that there are issues with physical groups, if so the group editor should identify if the set of physicals describes a topologically closed volume, and should have thrown an error in the latest version of SPIS.
You could also be doing something exotic with thin surfaces. I don’t remember all the do’s and don’ts there, but double check the manual for that. If this is built on a single .geo file, then I suspect throwing a “Coherence;” command in the .geo file before setting physicals would make sure you don’t create a mesh with overlapping tetrahedras.
Good luck!
