sponge layer damping
Sponge layer that damps the solution towards a reference condition near the farfield boundaries.

float·required·in m
Depth of the sponge layer, measured into the domain from the farfield boundaries.

float·required·in 1/s
Peak damping rate, applied at the farfield boundary and ramped to zero at 'distance' along a cosine profile.
