private subroutine calc_timestep_flow_cube(cfl, length, dt, timestep, nPoly)

Calculate time step based on a given CFL condition for a cube in a flow simulation.

This subroutine calculates the timstep according to the CFL condition. Please notice, that this routine can be applied for flow simulations only.
