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
