Dear everyone:
I want to write a program dealing with multiblock,but I don't known how to implement block-to-block B.C,especially when two block have different grids. All comments are much appreciated! |

Hello Zhao,
You can firstly generate two layers of ghost cells on every boundaries for each block. After that, what you need is to get the information for those halo cells from other blocks by either interpolation or transformation. Good luck Li |

or go straight to unstructured index addressing in your code so that there is nor boundary between blocks at all - there are just like any other internal cell faces even if they not not matched one-by-one.

This is surely the simplest solution. But, besides the quadrilateral elements obtained, what advantages will I have if I use this kind of connectivity?
