Class
Foam::matchedFlowRateOutletVelocityFvPatchVectorField
Description
Velocity outlet boundary condition which corrects the extrapolated velocity
to match the flow rate of the specified corresponding inlet patch.
Usage
\table
Property | Description | Required | Default value
inletPatch | Corresponding inlet patch name | yes |
volumetric | Set volumetric or mass flow-rate | no | false
rho | density field name | no | rho
\endtable
Example of the boundary condition specification for a volumetric flow rate:
\verbatim
<patchName>
{
type matchedFlowRateOutletVelocity;
inletPatch inlet;
value uniform (0 0 0);
}
\endverbatim
