[GiDlist] mesh quality
Posted: Sat Oct 11, 2003 11:32 am
When generating a 3D mesh, I get a big amount of tetrahedra with very
low angles.
( 10 degrees, and even lower .)
As a consequence the resulting mesh is of very poor quality.
I don't know how to correct or control this ill behaviour, in order to
get a mesh of better quality.
Especially in the case of quadratic tetrahedra where it is almost
impossible to correct each node by hand
( ie. with the tool : Meshing - Edit Mesh - Move Node ).
Can you give me a hint on this subject ?
Thanks in advance,
Andres
