Internalerror in findedge() TetGen Problem #36

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.

vtmk is totally different from this software and it is not using any of the code here (AFAIK). I'd recommend opening an issue with vmtk: https://github.com/vmtk/vmtk
