Usage

Example of the model specification:

partitioningModel
{
    // Mandatory entries
    type            cosine;
    alphaLiquid1    <scalar>;
    alphaLiquid0    <scalar>;
}

where the entries mean:

Property Description Type Reqd Deflt

type Type name: cosine word yes -

alphaLiquid1

Model parameters for threshold liquid phase fraction

scalar

yes

-

alphaLiquid0

Model parameters for threshold liquid phase fraction

scalar

yes

-

Note

Proposed threshold liquid fractions:
alphaLiquid1 0.1
alphaLiquid0 0.05
