Re: FEM MeshBoundaryLayer Documentation discussion thread

I think it is too difficult to make boundary layer working robust (working for different kind of meshing algorithm), how about just remove this feature? It is only useful in CFD case, where near wall velocity gradient is very big, if there is turbulent flow, there is a requirement of the first layer...

Re: Feature: add extra FemMesh mesh file export format, potentially usable by other solvers

the get_group_data and write_group needs to be reviewed: https://github.com/berndhahnebach/FreeCAD_bhb/commit/c5a63f782beae19668e0304c5f7b5fadd0fb5b51#diff-6c608a7e975af47e70a98bc0e50ff439R342-R661 ATM I have no idea why all this group code has changed and I have not tested your implementations. Wo...

Re: Feature: add extra FemMesh mesh file export format, potentially usable by other solvers

It is possible, by adding a new Property to Gmsh's DocumentObject, while most solvers still use V1 formats like Fenics. wait for Bernd's suggestion. move out *.geo from tmp folder is not quite necessary, it refers to brep goemetry file while is also in a temp path. the path info has been reported to...

Re: Feature: add extra FemMesh mesh file export format, potentially usable by other solvers

test result: it is fine to use this feature in GUI and nonGUI mode, except for 3 formats, see result report below There is some bugs I fixed, it is on my FreeCAD repo, just one commit top on Bernd's To https://github.com/qingfengxia/FreeCAD.git * [new branch] femgmshexport -> femgmshexport https://g...

Re: parametric pipeline between freecad and openfoam

Hello all, I am using the openfoam cfd workbench embedded in freecad. It’s working fine. Is there a way to achieve a parametric study, by varying a geometrical parameter (such as a distance or a pipe diameter) and makes the calculus automatically running during night? At the end, the aim is to plot...

Re: Feature: add extra FemMesh mesh file export format, potentially usable by other solvers

@qingfeng.xia It's been a while ... Are you still interested in merging this? I rebased it on master. See https://github.com/berndhahnebach/FreeCAD_bhb/commits/femgmshexport I may go for some refactor in gmsh tools. Means this should be merged before. To be merged it would need some testing and may...
