Re: [Gmsh] Visualising point data imported from MED files

Ha, ha:) I tried that, but failed, for the time being:) I only have the examples distributed with MED library to provide inspiration; That was the code: std::vector conn; for (i = 0; i < num; i ++) { conn.push_back(i); } ASSERT (MEDmeshElementConnectivityWr(fid, meshName, MED_NO_DT,

Re: [Gmsh] Visualising point data imported from MED files

Gmsh displays all meshes and post-processing data based on elements: so indeed you will need to add "point elements" (1 point for each vertex) in the med file in order to visualize it. Christophe > On 17 May 2018, at 14:56, Tomasz Koziara wrote: > > Dear Christophe, >

Re: [Gmsh] QMorph

thank you for your response. what i did was to read and STL file into GMSH and then i used the Recombine 2D with default option of Blossom but i got a quad dominant mesh with approximately 15-20% triangles. should this not have given the same results as the paper that was linked above? thanks On

Hi, Just in case, don't forget to check the options... http://gmsh.info/doc/texinfo/gmsh.html#Options ...To reset all options to their default values, use the ‘Restore default options’ button in ‘Tools->Options->General->Advanced’, or erase the General.SessionFileName and

[Gmsh] Strategies to mesh with hexaedra

Dear all, I am trying to use gmsh to mesh with hexaedra two volumes separated by a smooth non-flat interface. The entire volume is a cube. After many tries, I identified a meshing strategy but the results is not good enough. Is there a preferred strategy for the choice of a 2D and 3D

Re: [Gmsh] [GMSH] Surface mesh for 3D solids

Thank you for your response. But that is quite unexpected, since the normal vectors define the volume. So my question is, how can I make all the normal vectors point outward the volume? I am working with boundary element method and the normal vector orientation is really important to the method.
