Hmm, there is no VecScatterDuplicate so I think you'd have to make the vectors independently. Also as a side question, if I stored fxx and fyy inside a block vector, would I gain any performance in terms of MPI traffic? What about in 3D? It would be half the messages. Why are these vectors separate in the first place? pgp3uxLLJzYPu.pgp Description: PGP signature

It would be half the messages. Why are these vectors separate in the first place? I had not worked with block vectors before so just convenience i guess! When working with blocked vectors, how are items stored? Is it like fxx[0], fyy[0], fxx[1], fyy[1], ... or is it like fxx[0],fxx[1],...,fyy[0],fyy[1],...
