Set Meshing Options with Python?

first step = perfstepsstart
last step = perfstepsend
in python
and you can set the message level with
ngsolve.ngsglobals.msg_level = 0

thx very much!

i will try as soon as possible...

Hello,

I just tried the following python script:

from netgen.occ import *
geo = OCCGeometry("//STI01/STIWA/mail/ParM/ng/projects/parm/abc/Schuettblech.stp")
mesh = geo.GenerateMesh(meshsize.very_coarse, perfstepsstart=MESHCONST_ANALYSE, perfstepsend=MESHCONST_OPTSURFACE, curvaturesafety=5)
Draw(Mesh(mesh))
mesh.Export("//.................stl", 'STL Format')

does not work --> 'MESHCONST_ANALYSE' is not defined

what I did wrong?

(should) load python file '\\STI01\STIWA\mail\ParM\ng\projects\parm\abc\tmp.py'
Traceback (most recent call last):

Hi,

having a look at the code, I found a python enum "MeshingStep":
So just use to generate the mesh.

Best,
Christoph

thanks very much!

and is there a enum for MESHCONST_OPTSURFACE and MESHCONST_OPTVOLUME too?

regards, mario

The enum "MeshingStep" contains all these options (ANALYSE, MESHEDGES, MESHSURFACE, MESHVOLUME). I copied the export to python in my last post.
