24 Class
25  Foam::matchedFlowRateOutletVelocityFvPatchVectorField
26 
27 Description
28  Velocity outlet boundary condition which corrects the extrapolated velocity
29  to match the flow rate of the specified corresponding inlet patch.
30 
31 Usage
32  \table
33  Property | Description | Required | Default value
34  inletPatch | Corresponding inlet patch name | yes |
35  volumetric | Set volumetric or mass flow-rate | no | false
36  rho | density field name | no | rho
37  \endtable
38 
39  Example of the boundary condition specification for a volumetric flow rate:
40  \verbatim
41  <patchName>
42  {
43  type matchedFlowRateOutletVelocity;
44  inletPatch inlet;
45  value uniform (0 0 0);
46  }
