Dave, The global methodology is to: - create mesh - add hypothesis - add algorithms - compute mesh
The best way to start with is the samples scripts provided in the /SMESH folder (for instance volumic_mesh.py) The thing to know: the API is really ugly and not pythonic at all (one more time). Studies, algorithms and hypothesis are identified with an integer. For instance: aMesh = aMeshGen.CreateMesh(0,True) means that the created mesh is related to the study 0. Then: an1DHypothesis = StdMeshers_Arithmetic1D(0,0,aMeshGen) means that it's the hypothesis 0 for the study 0 an1DAlgo = StdMeshers_Regular_1D(1,0,aMeshGen) means that this algo has the id 1, and is applied to study 0 When all algo and hyp are created, they have to be added to the mesh: aMesh.AddHypothesis(aShape,0) # = add the hypothesis id 0 to the mesh aMesh.AddHypothesis(aShape,1) # = add the hypothesis id 1 to the mesh etc. THe hypothesis and algo control the way the boundary is discretized and how the elements are generated.
