How to turn off screen printing when executing "GenerateMesh"?

Hello,
I’m using “netgen” to mesh a 3D surface. Could you please let me know how to turn off the print to screen when running:
mesh = geo.GenerateMesh(maxh=maxh/scale)
Thanks.
MA

Example:
mesh = geo.GenerateMesh(maxh=maxh/scale)
set global mesh

Hi,
it should be enough to set

from ngsolve import ngsglobals
ngsglobals.msg_level = 0

Thanks Christopher.
Is it possible to set the logger level when I’m only using “netgen” and not “ngsolve”?
Thank you.
MA

Is there a way to set the “printmessage_importance” level for the whole “netgen” module on Python?
Thanks,
MA

There is the function SetMessageImportance in netgen.meshing.

Thanks Christopher.
It works and meshing messages are not printed but ONLY after the second execution of the code.
There might be something wrong behind?

Thanks, this worked.
