Cyclic BC versus directMappedPatch
Hi dear Foamers,
juste a comprehensive question, please: What is the difference between Cyclic BC and directMappedPatch? If I try to answer my self: Cyclic BC linkes respectively the cell of a BC-patch to another one. That means: * All the field values are the same * The two patches have exactly the same mesh directMappedPatch can do the same as Cyclic BC, but is much more versatile: * you do not link to patches, but copy some values from one patch to another (communication is only one way) * you can choose what fields are copied (U and not p, all but not k,...) * the patches do not have to be at the border of your domain. It can be "inside" * the meshes do not have to be equal: OF "mappes" the first on the second, interpolating the value on the mesh (with the problems with offset, sampleMode and so on) Am I right? Thanks a lot for correcting me. Julien PS: inserting tags, I saw directMappedBC. What are they? A mix between both? |
