simmetrix-to-pumi convert failure with 'no mesh' attribute on model entities #231

Description

@KennethEJansen

Convert fails in the following way:

MeshAdapt: worst element quality is 1.232585e-16

MeshAdapt: mesh adapted in 645.436791 seconds
number of tet 140547941 hex 0 prism 0 pyramid 0
mesh entity counts: v 23698418 e 164416865 f 281266370 r 140547941
APF FAILED: apf::Verify: vertex with 2 adjacent edges
centroid: (-0.20828, 0.49276, 0.570547)
based on the following:

  • vertex is classified on a model edge
    which is adjacent to 2 model faces
    and is a manifold boundary edge
    making the vertex "exposed" at the geometric boundary
    we would expect the adjacent edge count to be at least 3

When I draw a sphere at this location and take a clip plane through it, I see that it is on some model regions internal to the solid in the geometric model that I had put a SImmetrix No Mesh feature on while meshing.

Here is a picture proving there is no mesh at the offending point.

I am unclear if the verify is confused by unused model information. There is no mesh at this location

The planes clearly show there are no mesh vertices anywhere near the reported point. Is the point somehow reported wrong?
