NAME

generate_dw - generate waves for edw

SYNOPSIS

generate_dw N [-gaussian alpha rf] [-packet theta sigma k] [-droplet sigma] [-dr ocean | debroglie | scalar kstar] [-u]

DESCRIPTION

Generate_dw generates N x N initial date for a wave field suitable for evolution with edw.

By default it generates Gaussian noise with flat spectrum (alpha = 0) and 1-pixel smoothing length; i.e equavalent to 'generate_dw N -gaussian 0.0 1.0'.

With '-packet theta sigma k' it genenerates a gaussian profile wave packet with scale length sigma and wave vector k propagating in direction theta (in degrees). Use the -dr flag to set the dispersion relation.
