Hi everyone, I am trying to generate volume meshes for 3d models reconstructed using VMTK. I have .vtp files which have been clipped to create open inlets/outlets. The problem I am facing pertains to addition of cylindrical flow extensions. While adding the extensions (vmtksurfacereader -ifile foo.vtp --pipe vmtkcenterlines -seedselector openprofiles --pipe vmtkflowextensions -adaptivelength 1 -extensionratio 20 -normalestimationratio 1 -interactive 0 --pipe vmtksurfacewriter -ofile foo_ex.vtp) , it gives me a warning:
Warning: In /usr/css/opt/src/VTK/Graphics/vtkDelaunay3D.cxx, line 487 vtkDelaunay3D (0x163d420): 11 degenerate triangles encountered, mesh quality suspect. On giving the mesh command : it does the iterations and gives the error: ERROR: In /usr/css/opt/src/vmtk-0.8/vtkVmtk/Misc/vtkvmtkTetGenWrapper.cxx, line 310 vtkvmtkTetGenWrapper (0x95b5870): Invalid element found. TetGen command line options: pq1.414000Ys175.000000T1.000000e-08zQm Error: Invalid PLC. Facet (4865, 2324, 3008) (10113) is not a valid polygon. ERROR: In /usr/css/opt/src/vmtk-0.8/vtkVmtk/Misc/vtkvmtkTetGenWrapper.cxx, line 424 vtkvmtkTetGenWrapper (0x95b5870): TetGen quit with an exception. If I skip the extension part, I am able to mesh the model successively. Can someone please help me with this? Thank you.
