I want to mesh a 2D model, with quads only. But it has some specificities.
Simplified example
This mesh is a (very) simplified exemple of what i actually have. As you can see, I have surfaces like the one in the middle where I must have only 1 element in the width. I'm actually using mesh algorithm 8 (Frontal-Delaunay for Quads), recombining all surfaces, but it's not enough: I have still triangle.
I tried 2 options:
- mesh subdivision algorithm: I obtain a mesh with quads only with this algo, BUT it also divide the already created quads, therefore the surface where I need only 1 element in width contain now 2. Is there any possibility to apply the subdivision algorithm on specified surface?
- recombination algorithm 2 (quads only): It is not working. I get an error: '1D mesh cannot be divided by 2', and I don't really know why and how to solve it.
For more information: I'm importing a step geometry, modifying it with OCC, then define every mesh size on curves using transfinite curve (Maybe there is another way?). All of it is done using the Python API.
Any suggestion is appreciated.
