i like to add a inflate boundary layer to my mesh.
I choose this faces to add the inflate boundary layer.
This are the options for the inflate boundary layer (i. b. l.)
- Layers: 6
- Expansion Ratio: 1.3
- Min thickness 0.00001
- Final layer thickness: 0.027
The i. b. layers looks good on flat surfaces, but less on crooked faces.
Here are two example pictures.
Furthermore the i. b. layer create three illegal faces.
Checking faces in error : non-orthogonality > 70 degrees : 0 faces with face pyramid volume < 1e-13 : 0 faces with concavity > 80 degrees : 1 faces with skewness > 4 (internal) or 20 (boundary) : 0 faces with interpolation weights (0..1) < 0.02 : 0 faces with volume ratio of neighbour cells < 0.01 : 0 faces with face twist < 0.01 : 2 faces on cells with determinant < 0.001 : 0 Finished meshing with 3 illegal faces (concave, zero area or negative cell pyramid volume)
I looked into the documentation advanced settings for Hex-Dominat parametric but i found nothing, to avoid the face concavity or the face twist.
But im sure the are “adjusting skrews” to avoid the illegal faces and do a nice mesh without any illegal faces .
Which option i have to change to get a nice mesh ?
