Having problem with setting up project with external lib
I'm not sure if this is correct place, since my issue is most likely cmake related rather than c++, but I would like to ask anyway. So I'm trying to set up a project, which is new to me (this was usually done by someone else already). I would like to add the 3rd party library gmsh to the setup, but my CMake seems to incorrectly (or not all) link the lib. Source: over 1 year ago
Help With Self Study - Computational Physics
Depending on what you are planning on trying to do. Goma and OpenFOAMare both free to download and use. You can create a mesh with gmsh for free. Source: over 2 years ago
Looking to build a PC for Computational fluid dynamics - Budget around $2000 CAD
Mostly for work. I need to run some CFD models (OpenFOAM -https://openfoam.org/). But I also need to do pre-processing to create the models. I will use YADE (https://www.yade-dem.org/) and GMSH (http://gmsh.info/) for this. I think that for OpenFOAM it is more important to have good processors but for YADE and GMSH I think that I will also need a decent GPU. Source: over 3 years ago
Triangular meshing based on color gradient
I tried Gmsh with the script from Prof Geuzaine, and it work pretty well. Http://gmsh.info/ Script: Http://geuz.org/photos/cg/cg.geo. Source: about 4 years ago
