If your 3D case can be built from an extruded 2D case, you could try setting Mesh.Algorithm=8 to get right triangles (rather than equilaterals) and then use the Recombine Surface option to turn them into ... WebThe geometry itself is generated with a CAD engine. For example, create a geometry in Gmsh by doing (in the left panel): Geometry -> Elementary Entities -> Add -> Cylinder And then save the resulting geometry as "cylinder.step". You can then mesh the STEP file with: gmsh -3 -clmin 0.5 cylinder.step -o cylinder.msh. or.
