private subroutine calc_timestep_adv_cube(cfl, length, vel, dt, nPoly)

Calculate time step based on a given CFL number of cubes in a advection simulation.

This subroutine calculates the time step with respect to a given cfl number for simulations of advection processes. Please notice that this routine assumes constant advection speed.

Arguments
