Dear List, I have been trying to use the Python API but my meshing does not respond to the mesh size that I set when adding the points. I reproduced my problem in the following example. So no matter what value I set on lc¹, the surface always happens to have only four triangles.
Hope you can help me figure it out and be able to control the meshing. I am
also attaching the resulting 'MyTest.msh¹ file.
import gmsh
gmsh.initialize()
gmsh.option.setNumber("General.Terminal", 1)
gmsh.model.add("MyTest")
lc = 1e-4
gmsh.model.geo.addPoint(0, 0, 0, lc, 1)
gmsh.model.geo.addPoint(.1, 0, 0, lc, 2)
gmsh.model.geo.addPoint(.1, .3, 0, lc, 3)
gmsh.model.geo.addPoint(0, .3, 0, lc, 4)
gmsh.model.geo.addLine(1, 2, 1)
gmsh.model.geo.addLine(3, 2, 2)
gmsh.model.geo.addLine(3, 4, 3)
gmsh.model.geo.addLine(4, 1, 4)
gmsh.model.geo.addCurveLoop([4, 1, -2, 3], 1)
gmsh.model.geo.addPlaneSurface([1], 1)
gmsh.model.addPhysicalGroup(2, [1], 1)
gmsh.model.setPhysicalName(2, 1, "My surface")
gmsh.model.geo.synchronize()
gmsh.model.mesh.generate(2)
gmsh.write("MyTest.msh")
gmsh.finalize()
Thanks,
Alejandro
