vmtkmeshgenerator problem #37

Closed Lorenzomarta closed 2 years ago

Lorenzomarta commented 2 years ago

Hello everyone, I’m having trouble using the command “vmtkmeshgenerator” to obtain internal tetrahedral mesh, in particular starting with this command:

vmtk vmtkmeshgenerator -ifile sup3.vtp -skipremeshing 1 -volumeelementfactor 1 -ofile mesh.vtu

I obtain the following output:

[...] Duplicating background mesh. Internalerror in findedge(): Unable to find an edge in subface. ERROR: In ../vtkVmtk/Misc/vtkvmtkTetGenWrapper.cxx, line 431 vtkvmtkTetGenWrapper (0x7fa3b27ef170): TetGen quit with an exception. [...]

What do you suggest me to do? Thanks in advance.

I don't think this is the right place for your issue. This python wrapping of TetGen has nothing to do vtkvmtkTetGenWrapper.

I suggest you open an issue in vmtk: https://github.com/vmtk/vmtk

Seems https://github.com/vmtk/vmtk/issues/375 is tracking this or is at least related.
