Boundary mesh type

Outlet conditions are specified using the patch type entry in the $FOAM_CASE/constant/polyMesh/boundary file:

<patchName>
{
    type            patch;
    ...
}

General conditions

• Inlet outlet

Velocity conditions

• blocked return flow: see inlet outlet
• outflow: see zero gradient. Note: unstable for reverse flow
• Pressure-inlet outlet velocity

Pressure conditions

• static pressure: see fixed value
• Fan pressure
• Total pressure

Temperature conditions

• Total temperature

Turbulence conditions

• blocked return flow: see inlet outlet
• outflow: see zero gradient. Note: unstable for reverse flow
