I am new to blender and would like to use it as a kind of
pre-processor for CFD calculations with OpenFOAM
For this I am starting with the import of a STL file with
one solid. The aim is to define some additional
regions/materials based on some angles and regions. E.g. I
would like to select one triangle/face and automatically
select all neighbouring triangles as long as the connection
does not exceed a special angle.
It would be nice, if you have some meshing tips for me and
could point me to some tutorials!
In addition, is blender able to remesh the stl surface with
a defined curvature refinement?
Thanks in advance!
