[GiDlist] Mesh element quality

[Mark Smith]

Win98 GiD 6.3.0b

I am using gid to produce 100% linear triangle surface elements, using the
mesh quality facility with the quality criteria of minimum angle I can
highlight elements with minimum angle less than my requirement. My question
is there ant way for the meshing algorithm to be forced not to produce
triangles with a minimum angle less than my criteria say 15° (for example) ?

If there is no automatic way then under Utilities:preferences:meshing I
select surface mesher RSurf, enable mesh until end & automatic correct
sizes, unstructured size transitions 0.0 (slowest) and smoothing normal, are
these the best settings I can select?

Thanks in advance
Mark

P.S. any news on the version 7 for windows?

It is not possible to set the minimun angle to obtain, some surfaces would
be
impossible of meshing imposing this limit.

RSurf generate the mesh directly in 3D, and usually (not allways) this mesh
is better than
the one of Rfast (mapped from 2D to 3D).

Try smoothing HigthAngle to enhance some bad angles.

P.S. We hoped to have the official GiD version 7 this week.
