Attached the .msh file which CreateTopology do not work on it. Currently I am working with a windows 7 machine. It would be really nice if you will do some experiments with it. And I will try the other options which you mentioned. Once I find a way to solve my problem, I will inform you. best, Siming 2017-04-27 8:39 GMT+02:00 DILASSER Guillaume <[email protected]>: > Dear Siming, > > > > I can’t think of a reason why CreateTopology would not work on you model. > You should probably share your STL file with the mailing list so that we > can experiment with it. > > > > In the process of tutorial 13, the size of the mesh element is dictated by > a *MathEval* field, which may override the length you specified through > *Mesh.CharacteristicLengthMin*, but I am not sure of that.
