WebMay 30, 2011 · To simulate wave propagation, CFL and Blake's criteria are to be satisfied. Calculate the minimum wavelength. Take the mesh size (deltaX) as wavelength/n, where 'n' = 10 to 15 (in general). Critical time increment = tcr = deltaX/Vmax, where Vmax is the maximum wave speed. Time increment for time marching is taken as 0.75*tcr.
