Properties

• Coupling condition between a pair of patches
• Jump condition based on an underlying cyclic condition
• User defined fan curve of pressure rise vs velocity

Usage

The condition requires entries in both the boundary and field files. Mesh boundary file:

<patchName>
{
    type            cyclic;
    ...
}

Field file:

<patchName>
{
    type            fan;
    patchType       cyclic;
    jumpTable       <Function1>;
    value           uniform 0;

    // Optional entries
    phi             phi;
    rho             rho;
    uniformJump     no;
}
