Mesh with tris/quads
Mesh with tris/quadsPosted by Andreas G at May 31. 2007Hi,
I'm working on a python-script and therefore I want to mesh the generated faces (different number of edges [five,four,three])
with as many quadrangles as possible. Now my questions:
1.) Can Salome automatically generate a mesh with qudrangles (for quads) and triangles (for tris)?
2.) How can I combine two edges from a polygon, so that I get a quad-element?

Hi, Andi2.) for triangles use 2D Algorithm NETGEN1D-2D, in 2DHypothesis NETGEN_2D_Parameters use SetQuadAllowed( 1 )
Salome can automatically generate a mesh with quadrangles mostly
1.) for quads –use 2D Algorithm Quadrangle_Mapping and 2D Hypothesis Quadrangle_Preference
3.) to combine two edges from a polygon use 1D Algorithm Composite_side_discretisation together with 2D Algorithm Quadrangle_Mapping
Re: Mesh with tris/quadsPosted by Andreas G at June 04. 2007Hi again,
thanks Grigory for your answer. I know, that there are differnet Algorithms for quads and triangles. The problem is, that I have
one geometry, where I have quad elements and polygons. So now I tried in the Gometry tool of Salome to group the polygons and then I tried to make a mesh with this group as you discribe in your last post (3). This didn't work. There was a error: Mesh
computation failes and "Unexpected geometry. Face must have 4 sides but not 5."
The other question is: Can Salome generate a mesh with quads and tris at one geometry at the same time, or do I have to make group of quads and groups of tris and mesh them seperately?
Do you have a e-mail adress, so that I can send you my .hdf file for better understanding.
