Hello<br><br>I think you can just use the append dataset filter to combine the grids. This works fine with .pvd files: just load up the data<br>and select (highlight) all the data you want to combine and then apply the append dataset filter.<br><br>It certainly seems to work if the data have the same scalars etc.<br><br>Hopefully this is what you are looking at.<br><br>Lester<br>                                            </body>
