Mesh refinement and number of element vertices for triangular meshing

Hello Andreas,

thanks for your fast reply! Yes, I am doing some 2D meshing. I have now tried to use test_triangle.py, but I get the following error, which was reported in this forum before:

'boost::python::error_already_set'

I always got this problem if I define a refinement_func. I use boost from the ubuntu repository together with the latest version of meshpy from git, could that be a problem?

Cheers, Johannes

Hello Andreas,

thanks for publishing your MeshPy code! I am pretty new to python programming and have therefore some simple questions: I am trying to mesh some primitives eg. circles, rectangles etc. and combinations of them. Using the build method I can easily obtain the elements and points, but the mesh generator adds only few points to the ones I have provided with the MeshInfo object and the mesh is therefore quite coarse. I tried to change the values of the parameters volume_contraints and max_volume but this didn't really change anything. So I was wondering which parameters to use to refine my mesh. Also, I saw that there might be the possibility to set the number of element vertices for HO elements. How can I do that? In case, are the vertices equally spaced over the elements or do they follow some optimized rules (e.g. Legendre-Gauss-Lobatto)?

Thanks for your help! Cheers, Johannes
