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