Mesh

There are two output files containing mesh parameters (the 5D mesh consists of a 3D unstructured triangular mesh in configuration space and a 2D structured rectangular grid in velocity space): xgc.f0.mesh.bp and xgc.mesh.bp.

These files also contain quantities that can be useful to calculate various averages.
