I believe pyg4geometry has code to import STEP file via FreeCAD, mesh and output as gdml,īut I don’t know anymore. The current python coding is not very efficient, needs work on my. The code for reading in the gdml tesselate could be improved. Must be installed in a location that FreeCAD sees to check path FreeCAD uses from a command line terminal freecad -c The thing to remember is that FreeCAD stores it python libraries in a different place than the system version of python.

Gmsh install should be very similar to Windows. In theory yes, but it could be a bug that the Tessellated Sphere is wrongly positioned I would have to check, but yes the black wireframe is the World Volume box.

Unfortunately I have not found out, how to get individual stl/obj files from that.Please tell me that in this above image what is the black one (just above the sphere green one), is it my world from the GDML i shared with you ? meaning my sphere is not inside the world volume ?

You export this mesh as FEM mesh formats (*.unv, *.med, *.stl, *.dat, *.inp, *.vtk, *.vtu), I guess, which is an 'smesh' object.

I also found out, that there are gmsh groups from from within FEM workbench:

Using '-clscale 0.1' will divide this default length by 10. load a normal STEP file), a default length of 'objectsize/10' is used. lengths are provided (which is the case when you.

you can visually check/validate the obj files and their groups back in freecad/paraview 1) Specify a global scaling factor (using e.g.

and, if it is sufficient and snappyhexmesh is not needed, you can directly use the gmsh mesh (because of gmshToFoam).

you can use gmsh (which is one of the best open source mesher).

most this works from command line and can be automated.

the exported step file can be changed in dimensions and has same boundary conditions with the gmsh script and its numbering (at least if the same object within freecad is exported and only if this object has no other faces added or removed.) hem de mac os, windows ve linux iin versiyonlar mevcut.

It seems, of course a bit tedious, to generate stl/obj like this. So I search again for another approach and now I have this:įreecad -> export as step -> import into GMSH -> make physical groups -> mesh with gmsh -> export as default `.msh` file (or similar) -> use openfoams gmshToFoam script -> then use `surfaceMeshTriangulate` to get the stl/obj. Is not very good, because it is not very scriptable, and everytime some geometry is changed in dimension and is new generated you have to set the colors again. The color section approach, specified in the first link of my post #5 Which I think again is not correct because, it is not watertight. Set the path in FEM - Gmsh preferences to /opt/gmsh-4.8.4-Linu圆4/bin/gmsh.

Copied and extracted it into the opt folder.

Download the latest stable version from the gmesh website. The method which derekm explained, is probably the same as in Freecad: how to prepare a mesh suitable for OpenFOAM?, I uninstalled gmsh using the MX Linux package manager.
