An atmospheric boundary layer velocity can now be added to the gas side
of the wave modelling. The wave superposition class has been given a
run-time selection mechanism, and a derivation added which includes gas
atmospheric boundary layer modelling. This modelling is therefore
available in both the wave boundary conditions, and in setWaves.
This functionality can be selected in the constant/waveProperties file
by supplying a "type" entry and a number of parameters controlling the
boundary layer. For example:
In constant/waveProperties:
type waveAtmBoundaryLayer;
// properties specifying the wave modelling ...
UGasRef (10 0 0);
hRef 20;
hWaveMin -2;
hWaveMax 3;
UGasRef is the gas velocity relative to the liquid, at the height, hRef,
relative to the wave model origin. hWaveMin and hWaveMax describe the
range of the wave elevation; it is non-trivial to calculate this from
the wave models themselves, so it is required as an input.
The base wave superposition class can be selected with "type wave;", but
also selects by default when the "type" entry is omitted, so the change
is backwards compatible.
