Hi I am trying to remesh an STL file to create a Tetrahderon.
My code looks like based on info on the web

I used the gmsh-api for python
https://gitlab.onelab.info/gmsh/gmsh/blob/master/README.txt
The code I used is below for the gmsh-api
import math
import gmsh_api
import gmsh_api.gmsh as gmsh
gmsh.initialize()
gmsh.option.setNumber("General.Terminal", 1)
gmsh.option.setNumber("Mesh.Algorithm", 8);
gmsh.option.setNumber("Mesh.CharacteristicLengthMin", 1);
gmsh.option.setNumber("Mesh.CharacteristicLengthMax", 2);
gmsh.option.setNumber("Mesh.Optimize",1)
gmsh.option.setNumber("Mesh.QualityType",2);
gmsh.merge("C:/2_FuzzyClassification/brainmodel/brainModelscriptacvd.stl")
n = gmsh.model.getDimension()
s = gmsh.model.getEntities(n)
l = gmsh.model.geo.addSurfaceLoop([s[i][1] for i in range(len(s))])
gmsh.model.geo.addVolume([l])
print("Volume added")
gmsh.model.geo.synchronize()
gmsh.model.mesh.generate(3)
gmsh.write("C:/2_FuzzyClassification/brainmodel/example.msh")
gmsh.finalize()
My Code
def meshObjSTL(obj, dim) :
obj.Mesh.write('/tmp/transfer.stl')
bbox = obj.Mesh.BoundBox
ml = maxCord(bbox) / 10
print('Mesh length : '+str(ml))
gmsh.option.setNumber("Mesh.Algorithm",8)
gmsh.option.setNumber("Mesh.CharacteristicLengthMax", ml)
gmsh.option.setNumber("Mesh.CharacteristicLengthFromCurvature", ml)
gmsh.option.setNumber("Mesh.CharacteristicLengthFromPoints", ml)
gmsh.option.setNumber("Mesh.Optimize",1)
gmsh.option.setNumber("Mesh.QualityType",2)
gmsh.merge('/tmp/transfer.stl')
n = gmsh.model.getDimension()
s = gmsh.model.getEntities(n)
l = gmsh.model.geo.addSurfaceLoop([s[i][1] for i in range(len(s))])
gmsh.model.geo.addVolume([l])
print("Volume added")
gmsh.model.geo.synchronize()
gmsh.model.mesh.generate(dim)
print('Mesh Generated '+str(dim))
gmsh.model.mesh.renumberNodes()
But crashes with no output ( Code is part of a FreeCAD workbench )
