calc_timestep_nerplanck_cube Subroutine

private subroutine calc_timestep_nerplanck_cube(cfl, length, dt, nPoly)

Calculate time step based on a given CFL number of cubes in a Nernst-Planck simulation.

This subroutine calculates the time step with respect to a given cfl number for simulations of Nernst-Planck equations. Please notice that this routine assumes constant material parameters.
