Setting minimum dihedral angle when meshing
Posted: Mon Mar 07, 2016 4:57 pm
Hi,
I am trying to generate a mesh for my geometry in Simvascular using the boundary layer meshing option. When I generate the mesh it appears to complete the surface meshing procedure and then passes off to tetgen where I get the following error:
Found two nearly self-intersecting facets.
1st: [7, 8, 6] #639713280
2nd: [7, 8, 18695] #2
The dihedral angle between them is 0.0863066 degree.
Hint: You may use -p/# to decrease the dihedral angle tolerance 0.1 (degree).
ERROR: TetGen quit and returned error code 3
I then attempted to decrease the dihedral angle tolerance by disabling the -q flag and using 'Other user specified flags: q1.4/0.05' instead. I still received the same error, am I using the user defined flags incorrectly?
Also does anyone know where I could find some information on the surface meshing and boundary layer meshing implementation in Simvascular?
Kind regards,
Tim
