You need to use a geographic projection for the mesh or a conventional Cartesian coordinate system. See examples/twocells/twotet4-geoproj for an example that uses a mesh in a geographic projection.

But, I am afraid Pylith convert point list in ouput_points.txt file and assuming that list points are 3D cartesian.
