I'll have a go at writing Xdmf files.<br>

Am I right in thinking that VTK files are written sequentially?<br></div></blockquote><div><br></div><div>Yes, it is a rightly despised format, suitable only for beggars and serial jobs :)</div><div><br></div></div></div></blockquote><div><br></div><div>By "rightly despised format", I hope you are talking about the legacy VTK files (the traditional .vtk extension).</div><div>The new XML formats with <AppendedData encoding="raw"> are quite easy to write in parallel with MPI/IO (at least *.vtu files, which is what I'm using).</div></div></div></blockquote><div><br></div><div>That is true.
