Description
|
|
This boundary condition sets the pressure gradient to the provided value
|
|
such that the flux on the boundary is that specified by the velocity
|
|
boundary condition.
|
|
|
|
Example of the boundary condition specification:
|
|
\verbatim
|
|
myPatch
|
|
{
|
|
type fixedFluxPressure;
|
|
}
|
|
\endverbatim
