<BODY style="MARGIN: 4px 4px 1px; FONT: 10pt Tahoma">Yes, I want to break the mesh down. I want to partition the entire data set into 4 chunks. Does anyone have a link to sample code? I tried to use the distributed data filter, but was unsuccessful in its implementation. I assume the file format would still be a pvtu and 4 vtus.<BR><BR>>>> "Berk Geveci" <berk.geveci@kitware.com> 12/28/2009 10:18 PM >>><BR>or the distributed data filter in VTK.<BR><BR>On Mon, Dec 28, 2009 at 5:57 PM, Dominik Szczerba <dominik@itis.ethz.ch> wrote:<BR>> -----BEGIN PGP SIGNED MESSAGE-----<BR>> Hash: SHA1<BR>><BR>> I don't think this is intended to partition your mesh, or at least I<BR>> would be highly (if positively) surprised.<BR>><BR>> Do you not mean to partition a mesh for e.g. domain decomposition<BR>> purposes or other parallel applications?
