<div dir="ltr">Hi Daniel,<div><br>The datasets that you describe are what most computational physics datasets are like. The geometry remains fixed while the scalars on the geometry change with time. The Ensight Gold format is one that I use often. It has very nice support for time series data where there is just one geometry file with a set of changing scalars on the geometry.<br><br><a href="http://www-vis.lbl.gov/NERSC/Software/ensight/doc/OnlineHelp/UM-C11.pdf">http://www-vis.lbl.gov/NERSC/Software/ensight/doc/OnlineHelp/UM-C11.pdf</a><br><br>I'm not sure exactly what you are asking for in your original question. Do you want the Kitware guys to write a filter that can read some sort of simulation data formatted in a specific way into Paraview? They would need more information about the format that you are using i.e. how is the data structured, etc. <br><br>Hope this helps,</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Jan 23, 2017 at 1:31 PM, Daniel Frisch <span dir="ltr"><<a href="mailto:daniel.frisch.kit@gmail.com" target="_blank">daniel.frisch.kit@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hello, <div><br></div><div>in Biomedical Engineering we often work with large datasets where the geometry doesn't change over time but the scalar values change.
