| Summary | 0004033: Can cyclicAMI isreplaced by ncc for Dynamic Mesh Refinement in plate two-phase flows | ||||
| Description | In studying the two-phase plate flow problem with periodic boundaries, I found that using cyclicAMI boundaries and mesh refinement will cause mass loss. In Openfoam10, a new non-conformal coupling (NCC) that can replace cyclicAMI was introduced. But I found It seems that NCC only applies to patches which partially overlap. Can the NCC be applied to two completely separate patches? Is it suitable for mesh refinement on periodic boundaries? | ||||

NCC can do everything AMI did (and more), including fully overlapped patches. In contrast to AMI, you have to specify a non-overlapping boundary condition just in case the overlap isn't calculated to be exactly 100%, but in a fully overlapping case this should not be used. NCC works with adaptive refinement, but only in dev. Read the following article and look at some tutorials. https://cfd.direct/openfoam/free-software/using-non-conformal-coupling/ Not a bug report. Closing. |
