temperatureCoupledFvPatchScalarField

Description

Coupled boundary condition that enforces continuity for the temperature field between two regions with different material properties.

Warning

This boundary condition assumes that the same boundary condition is applied to a pair of regionCoupledOFFBEAT patches, which are coupled using the AMI (Arbitrary Mesh Interface) mapping algorithm.

Options

The temperatureCoupled fvPatchField can be selected in the patch subdictionary inside the boundaryField subdictionary of the temperature field.

Parameters in patch subdictionary for temperatureCoupled:

patchType Specifies the type of underlying fvPatch and must be set to regionCoupledOFFBEAT.
kappa The name of the conductivity field. By default, it is set to "k", which is the field name for conductivity used by the OFFBEAT material class.
value Specifies the initial value of the patch temperature field.

Usage

Here is a code snippet of a typical patch field dictionary:

"fuelOuter|cladInner"
{
    type            temperatureCoupled;
    patchType       regionCoupledOFFBEAT;

    kappa           "k";

    value           $internalField;
}
