WebTo generate a 2D mesh and a 3D mesh adapted to simulation, we propose to use GMSH. Using FreeCAD, export your mesh in “. brep ” format. Load the “.brep” file in GMSH. 2. Options Several options are available to optimize your mesh. We recommend to use the “MeshAdapt” algorithm for the 2D generation. WebAll gmsh options (General, Geometry, Mesh) can be written with the same syntax as writing directly in a geofile. The full list of options available is in py2gmsh/Options.py # mesh options my_mesh . options .

WebMay 2, 2011 · Rep Power: 15. Hi All, I am a new user of Gmsh. I created the geo file and meshed it using Gmsh GUI. From the mesh option, I changed the element size factor to create finer mesh, e.g I used element size factor 0.05, 0.03, and 0.01. However, I did not get any explanations about element size factor. lastenneuvola seinäjoki
