> user must click 'Add reference' button, then click goemetry, it is not bug but I miss out the user manual Issue 2: in reference box, selected geometry element will not show up until next element is clicked > solved, my stupid error after copy and paste Issue 1: FemMeshBoundaryLayer, properties can not been changed in taskpanel: 2 of then can be updated now, only one left: thickness The ends of boundary layer is not good, I am not sure if fan angle could help Set up boundary mesh parameters could be trick, so try my 2D case first for testingįreeCAD _gmsh_3d_ boundary_layer_meshing.png (397.27 KiB) Viewed 6562 times I can get result, but not sure it is realisticģD is also possible, but boundary layer can only been viewed in wireframe view modeģD data file is too big to upload to this forum. Only one boundary setting bbject/Field can be applied, but multiple boundary faces can be selected.ĢD meshing can get a result and shown up in taskpanel.Īlthough solid mechanics does not need a boundary layer, but it should not hurt. but anyway, you can substitute the coarse mesh generated by FEM/CFD workbench with some better one after the initial evaluation in GUI.Īlso mentioned, OpenFOAM CFD workbench use cfmesh and snappyHexMesh of OpenFOAM for boundarlyer refinement. Gmsh boundary meshing is not robust like commercial tool like Ansys workbench, so it may fail for complex geometry. This function is built on his work of FemMeshRegion, Thanks for bernd. Now I am turning into coding, a new class 'FemMeshBoundaryLayer' is added, holding setup information. The boundary layer is hard to see, meshing bisect may illustrate it better.
