Control of 3D elements layers considering model contour.
Hello dear community and dear professor. Can I adjust the size of 3d elements depending on the layer ? I need gmsh to create larger elements in the inner layer, but smaller elements in the outer layer. I am looking at mesh size fields, but I can only create primitives like sphere or box. I would like to take into account the contour of the model. What tools can help me with this task? I would like gmsh to preserve 3d elements like tetrahedrons, so maybe I can't use the extrude tools as they will convert tetrahedrons to prisms. Could you please give me an example of a script that handles this task. Thank you for your attention and have a nice day !
