I was faced with the following problem: I have a nice unstructured mesh 2D mesh in GMSH, and I want to extrude this mesh with a certain growth ratio to a 3D mesh. The extrude command in GMSH lets you easily make an extrusion were all the layers are the same height, but … WebTo refine the mesh in the injection zone, the characteristic length of each layer entity is increased the farther we get from the injection point. Note that layers are defined such that their characteristic lengths are increasing. This is because Gmsh keeps the first node defined in the geometry in case it detects duplicated nodes.
