the condition number (mesh quality metric) on all surfaces are good but trelis cannot generate a mesh. It says:
mesh vol 158
Meshing Volume 158 (Volume 158)
Beginning C A M A L - T E T M E S H (Ver 6.1-0) session
ERROR:
Found edge/face intersection: 19 86 with 4 87 413
ERROR:
Unable to generate empty mesh End C A M A L - T E T M E S H session
ERROR:
Volume 158 (Volume 158) meshing unsuccessful.
How do I locate this edge/face intersection so that I can fix it?
I see that you are getting CAMAL errors. I am not getting these errors. You might be using an older version of Trelis. Since 15.1 we updated the tetmesher.
In Trelis 15.1.5, I opened your .cub file and subtracted the free surfaces from the two layer volumes, then merged and tetmeshed.
reset
open “irpina_topo_22faults.cub”
subtract body 2 4 9 to 26 29 30 from vol 6 8
merge all
vol all scheme tetmesh
set keep invalid mesh on #(the mesh is actually valid)
mesh vol all
draw tet in tri in surf 40 to 48
“draw tet in tri in surf 40 to 48” draws the tet elements on the inner surfaces in the upper layer, just to show you that they meshed.
