Unable to mesh imported vtp surface
Posted: Wed Mar 14, 2018 3:11 am
Hi Everyone,
Thanks for the effort you're putting in this great tool. I am starting to get familiarized with the software in Ubuntu 16.04.
I am having trouble with meshing an imported surface (aorta) from a triangulated vtp file. I can succesfully do a surface remesh in the imported open surface, in the imported closed surface and in the surfaced capped within Simvascular. All the baoundaries in every case seem to be correct.
However, when I try to run the volume meshing with the suggested edgelength, I receive the error "Failed in generating mesh". Meshing with TetGen via VMTK in the same model with the same edgelength does the job. Furthermore, in the terminal log from which I ran Simvascular I get:
Checking surface mesh
Regions: 1
Number of Free Edges on Surface: 0
Number of Non-Manifold Edges on Surface: 0
#67.569# [VtkError] ERROR: ERROR: In /home/hongzhi/ForSV3_201603/Distribution_Use_Server/SimVascular/SV_Source/Code/ThirdParty/vmtk/simvascular_vmtk/vtkvmtkPolyDataSurfaceRemeshing.cxx, line 178

Converting to TetGen...

Array name does not exist in polydata. Regions must be identified and named prior to this function call
Could not add facet markers to mesh
For some reason, mesh is not loaded! TetGen cannot be run.
TetGen Meshing Started...
Error: The point set is trivial.
ERROR: TetGen quit and returned error code 10
Any clues?
Thanks a lot,
Rodrigo
