Class
Foam::mappedFlowRateVelocityFvPatchVectorField
Description
This boundary condition maps the flow rate from a neighbouring patch to
this patch, then uses it to set a corresponding velocity in a direction
normal to the patch.
Usage
\table
Property | Description | Required | Default value
nbrPhi | name of flux field on neighbour mesh | no | phi
phi | flux field name | no | phi
rho | density field name | no | rho
\endtable
Example of the boundary condition specification:
\verbatim
<patchName>
{
type mappedFlowRateVelocity;
value uniform (0 0 0);
}
\endverbatim
This boundary condition can only be applied to patches that are of
mapped type.
