Mesh Validation with CUBIT

1. build mesh in CUBIT
2. run acdtool (acdtool mesh stats mesh.ncdf) to check euler numbers for the mesh.
3. check mesh quality of all volumes with the "Distortion" metric within CUBIT
4. fix improve the mesh in these areas, using CUBITif negative values are found
5. repeat until mesh achieves the recommended values are achieved for the various quality metrics.looks reasonable
6. run acdtool (acdtool mesh stats mesh.ncdf) to check euler numbers and general quality for the mesh.
7. run acdtool (acdtool mesh check mesh.ncdf) to check for invalid elements in the mesh.
8. run acdtool (acdtool mesh fix mesh.ncdf mesh.fixed.ncdf) to fix any invalid elements in the mesh.

Mesh Validation with ParaView

1. build mesh in CUBITrun acdtool (acdtool mesh stats mesh.ncdf) to check euler numbers for the mesh.
2. load mesh in ParaView
3. apply Mesh Quality filter
4. look at 2D Spreadsheet View of quality to find cutoff quality for n worst elements
5. apply Threshold filter, to select only elements with quality worse than cutoff
6. optionally glyph the thresholded vertices with spheres so that they show up
7. optionally make mesh surface visible, but transparent to give context for where the meshing errors are.
8. fix the mesh in these areas, using CUBIT
9. repeat until mesh achieves the recommended values are achieved for the various quality metrics.
10. run acdtool (acdtool mesh stats mesh.ncdf) to check euler numbers for the mesh.
11. run acdtool (acdtool mesh check mesh.ncdf) to check for invalid elements in the mesh.
12. run acdtool (acdtool mesh fix mesh.ncdf mesh.fixed.ncdf) to fix any invalid elements in the mesh.
