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;
}
