Re: [Gmsh] Line loop and Open cascade

Is it possible to extract associated line loop with each rectangle command so that I can define a plane surface with line loops that forms holes of first ones ? Best Regards, Sathyanarayan Rao, PhD student Earth and Life Institute/Environmental Sciences (ELI-e)

Re: [Gmsh] Line loop and Open cascade

If I put SetFactory("OpenCASCADE"); in the first line, then it gives me different error saying "unknown line loop with tag1" // mesh size description SetFactory("OpenCASCADE"); cl_1 = 0.3; cl_2 = 0.02; cl3= 0.02; Mesh.CharacteristicLengthMax = 40; extend = 15; // define inversion

[Gmsh] Line loop and Open cascade

Dear gmsh team, Is it not possible to use both line loop type surface definition and open cascade rectangle. I always have problem with using both. For example in the below code, surface 105 is unrecognized ! // mesh size description cl_1 = 0.3; cl_2 = 0.02; cl3= 0.02; Mesh.Charac
