Hi. I start to learn SU2_PY. For FSI problems,in FSIinterface.py, there is line:


self.nLocalFluidInterfacePhysicalNodes = self.nLocalFluidInterfaceNodes - self.nLocalFluidInterfaceHaloNode


I am confused what is HaloNode of fluid mesh? is it connected with dual mesh?

Does anybody know this and is there figure show this? I am looking forward to your response.



Thank you very much!

Halo nodes are created during partitioning of the domain for parallelization.
Each MPI rank (i.e. processor) gets a part of the original domain. These smaller parts overlap slightly, some nodes appear in two partitions, one "owns" the node the other does not, for the latter that node is a halo node.
