24 Class
25  Foam::wavePressureFvPatchScalarField
26 
27 Description
28  This boundary condition provides a wavePressure condition. This sets the
29  pressure to a value specified by a superposition of wave models. All the
30  wave modelling parameters are obtained from a centrally registered
31  waveSuperposition class.
32 
33  This functions like an outletInlet condition. Faces on which the flow is
34  leaving the domain have a value set by the wave model. Faces on which the
35  flow is entering the domain have the gradient set. This gradient is
36  calculated numerically by evaluating the wave model on both the patch face
37  and the adjacent cell.
38 
39  Use of this boundary condition triggers a consistent behaviour in the
40  corresponding velocity and phase-fraction conditions.
41 
42 Usage
43  \table
44  Property | Description | Req'd? | Default
45  U | name of the velocity field | no | U
46  rho | name of the density field | no | rho
47  \endtable
48 
49  Example of the boundary condition specification:
50  \verbatim
51  <patchName>
52  {
53  type wavePressure;
54  U U;
55  rho rho;
56  }
