In the following code, the geometry is modeled using three rectangles: lc = 0. Gmsh is a 3D finite element mesh generator with built-in pre- and post-processing facilities. unstructured mesh possible for any 2D form can be a quick fix rather than dividing subdomains down to quads and. such as GMSH (described in Sect.3.2) and TetGen (Si, 2015). In such cases, you should partition the problem geometry into distinct rectangles (planes with four corner points) so the Trasnfinite option could be applied to them. GINA can generate structured meshes in 1D (line), 2D (quad or triangle) and 3D (prism and. In your file, the plane is constituted from six points and Gmsh can't mesh it structured. > I know that I can reach this dividing the polygon in two polygons with 4.
