	6th order finite difference derivative of a function on realspace grid More...
subroutine, public	rs_methods::setup_grid_axes (pw_grid, x_glbl, y_glbl, z_glbl, x_locl, y_locl, z_locl)
	returns the global axes and the portion of the axes that are local to the current mpi rank More...
subroutine, public	rs_methods::pw_mollifier (pw_pool, zeta, x_glbl, y_glbl, z_glbl, pw_in, pw_out)
	convolutes a function with a smoothing kernel K_\zeta v * K_\zeta K_\zeta is the standard mollifier defined as: K_\zeta(x) = \frac{1}{\zeta^3} K(\frac{x}{\zeta}) where K(x) = \kappa \exp (\frac{1}{|x|^2 - 1}), if |x| <= 1 = 0, otherwise More...
