Enables users to set field values in the domain, irrespective of the local flow conditions.
Properties🔗
Downstream fields outside the region constrained will continue developing normally.
No information will be added to the log file other than the identification of the constraint at the start of the simulation.
Usage🔗
The constraint is available for all primitive field types, i.e. scalar, vector,
sphericalTensor, symTensor and tensor, where the type
entry is set as
type <type>FixedValueConstraint
For example, the scalar variant can be applied to the turbulence k
and
epsilon
fields using:
fixedValue
{
type scalarFixedValueConstraint;
active yes;
selectionMode cellZone; //cellZone or all
cellZone porosity;
fieldValues
{
k 1;
epsilon 150; // any field values can be modified, including scalars.
}
}
