If you are not an intended recipient, you should not disclose, use or copy this information. hi everyone : Gmsh Reference Manual said : There are three ways to specify the size of the mesh elements for a given geometry: 1 Mesh.

I'm sure there is a way to do this in the GUI, but I only really use the script input myself here's how to do it that way.

Speci cation of the mesh (mesh size, element types, which mesh generator to use.

(referenced as the background field) but theĮlement sizes in different regions all appear the A geometry modeling software with CAD engine. To set the mesh size for an initial field, thenĭefined a new second field for each surface usingĬan you tell me how to combine these fieldĭefinitions, please? I tried Min, Max, MathEvalĪnd MinAniso types to define my last field I went on with it, attempting to define theįield for more than one surface, using MathEval Open the geo file and click on Mesh/define/3D. mesh.png There is some potential there Place the Brep and geo file in the same directory. freecad.png With a very simple geo file I got this. I created a CompoundFilter and exported as a Brep.

Next message: pos to msh2 convertion ? Did not contact the devs but played a little bit with Freecad and gmsh instead.

Previous message: Mesh size definition referring to surface or volume numbers.

Mesh size definition referring to surface or volume numbers. I get the warning regarding the double nodes.Mesh size definition referring to surface or volume numbers. generate_mesh( geom, dim= 2, verbose= True)) # Mesh element size lcar = 750.0 points = '' 'set up pygmsh geometry' '' geom = pyg. But when I use my implementation which are somehow similar to yours: def mesh_world_csem( start=, end=):

I can confirm this with Gmsh 3.0.6, Ubuntu 18.04.2 LTS. When I run your example, everything works as you experienced. Mix of 8-node quadrilateral (QUAD8) and 6-node triangle (TRIA6) elements QUAD8/TRIA6 mixed mesh provided by CodeAster. However, the number of nodes and elements are slightly different. It is almost identical to that provided by CodeAster. But maybe this is also something for scikit/pgmsh? The mesh generated by this process is shown in the adjacent figure.

I used and modified their fixed_double_nodes - routine for my application. Lurking around in the sfepy manual/code, they have a conversion script to handle these kind of things, described in With two surfaces it automatically creates these 'double' nodes. From what I have learned regarding gmsh is that it creates a mesh containing duplicate vertices on the handle/shank interfaces.
