Dear all, For concerning more general geometry of physical domain, for some situations, we need to apply the multi-block mesh. The attached figure (or alternatively the following link) illustrates one of examples.
https://dl.dropbox.com/u/17189529/share_documents/IMAG0003.jpg Have you ever dealt with such kind of case with application of the PETSc object 'DA' ? Suppose we build multiple DA(or DM) for governing the multi-block data structure, in other words, we respectively build a DA for each block of mesh. Especially in parallel computing, how can we manage and control the communications between blocks of data accurately and efficiently? And, how can we ensure the correctness of parallel computational results? I wonder whether some possible application of PETSc object 'DA' (or DM) is sufficient for dealing with cases in multi-block mesh. Sincerely regards. Chuei-Ching Chiou -- Chuei-Ching Chiou, Ph.
