Class
Foam::noSlipFvPatchVectorField
Description
This boundary condition fixes the velocity to zero at walls and assumes
the walls are stationary.
For stationary walls with sliding vertices, e.g. engine liners, the normal
component of the velocity is set from the wall face-flux to ensure
continuity.
Usage
Example of the boundary condition specification:
\verbatim
<patchName>
{
type noSlip;
}
\endverbatim
