| Class | |
| Foam::fixedValueInletOutletFvPatchField | |
| Description | |
| This boundary condition sets a fixed value. When the flow direction is | |
| inwards this acts exactly like a fixed value condition. In the presence of | |
| outflow, however, this condition approximates the fixed value constraint in | |
| advective terms by fixing the gradient instead. | |
| This condition is not likely to be used on its own. It is more suitable as | |
| a base class for conditions that need to specify the value of a field even | |
| when the flow reverses. | |
| Usage | |
| \table | |
| Property | Description | Required | Default value | |
| phi | Name of the flux field | no | phi | |
| \endtable | |
| Example of the boundary condition specification: | |
| \verbatim | |
| <patchName> | |
| { | |
| type fixedValueInletOutlet; | |
| phi phi; | |
| value 0; | |
| } | |
| \endverbatim | |
