vacuum type
The arrays here are of the form:
H, G: (n_loc,n_loc)res: (n_mod_X,n_mod_X)where n_loc is the number of points in the boundary, i.e. a subset of n_bnd.
For vacuum style 1, the vacuum is assumed to be equidsitant in the coordinate along the magnetic field lines and, if there are multiple field lines, also in the field line label \(\alpha\). The limits on the angles are assumed to be given by the global variables grid_vars.min_par_x, grid_vars.max_par_x and grid_vars.min_alpha, grid_vars.max_alpha.
For vacuum style 2, there is an additional angle ang. It is composed of the angles along the magnetic fields (which refers to angle_1 in the discussion of grid_vars.grid_type), of which there can be multiple, but the total sum must be equal to n_bnd.
