Description🔗
The fixedFluxPressure
is a pressure boundary condition to
set the pressure gradient to the provided value such that the flux on
the boundary is that specified by the velocity boundary condition.
This condition ensures the correct flux at fixed-flux boundaries by
compensating for the body forces (gravity in particular) with the
pressure gradient.
Usage🔗
The condition requires entries in both the boundary
and field files.
Boundary file🔗
<patchName>
{
type patch;
...
}
Field file🔗
<patchName>
{
// Mandatory entries
type fixedFluxPressure;
// Inherited entries
...
}
where:
Property | Description | Type | Required | Default |
---|---|---|---|---|
type |
Type name: fixedFluxPressure

word | yes | - |
The inherited entries are elaborated in:
- fixedGradientFvPatchFields.H
- updateableSnGrad.H
