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;
}
