Class
Foam::fv::fixedValueConstraint
Description
Constrain the field values within a specified region.
Usage
For example to set the turbulence properties within a porous region:
\verbatim
porosityTurbulence
{
type fixedValueConstraint;
cellZone porosity;
fieldValues
{
k 1;
epsilon 150;
}
}
\endverbatim
