The open source CFD toolbox
Cyclic

# Properties

• Coupling condition between a pair of patches
• Faces on each coupled patch must have the same topology, i.e. they must have collocated points such a one-to-one mapping exists between the faces on each side.
• The coupling is treated implicitly using the cell values adjacent to each pair of cyclic patches
• The face values are determined using linear interpolation between the cell values

# Usage

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

<patchName>
{
type            cyclic;
neighbourPatch  <coupled patch name>;
transform       <transform type>;
...
}


Field file:

<patchName>
{
type            cyclic;
}
