Computes the blending coefficient employed by blended divergence schemes, giving an indicator as to which of the schemes is active across the domain.
Blended schemes combine contributions from two schemes, i.e. \(\phi_1\) and \(\phi_2\), using a weight field, i.e. \(w\), such that the effective scheme value, i.e. \(\phi_{eff}\), is computed as follows:
\[ \phi_{eff} = w \phi_1 + (1 - w) \phi_2 \]
The weight field, i.e. \(w\), is surface field and converted to a volume field for easier post-processing by setting the cell value to one minus the minimum of the face values.
This conversion leads to blending indicator field whose values mean:
0 = scheme 0 1 = scheme 1 0-1 = a blend between scheme 0 and scheme 1
Operands:
| Operand | Type | Location |
|---|---|---|
input | - | - |
output file | dat | $FOAM_CASE/postProcessing/<FO>/<time>/<file> |
output field | volScalarField | $FOAM_CASE/<time>/<outField> |
