Thank you for your patience. I don’t have a solution yet, but this is probably due to a bad mesh. Others may provide additional guidance.
A few points:
- The STL file looks better, but look at the output:
STL file(s) successfully read.
Total number of facets read =134588
Number of valid facets =104889
Number of ignored facets = 29699
This is an indication small triangles are still present. You may get better results by reducing the facet angle tolerance and decreasing the intersection tolerance.
-
You are still modeling the outside of the geometry. Make sure you look at the mesh by saving a vtk file. Uncheck the “External Flow” box in Mesh> Mesher
-
Your domain box cuts the stl on the side. Increase the x and z range to ±0.296 m
-
Some of the mesh tolerance will need to be adjusted due to the highly stretched nature of the mesh.
