<div dir="ltr"><div>Hi,<br><br></div>The XML readers and writers don't properly support time so currently the best way would be to create a pvd file which would contain the time and time step information. I don't know of anything in VTK or ParaView that writes out pvd files (I only see a vtkPVDReader in ParaView) but the format is meant to be simple. I would suggest doing it directly in the Catalyst Python script through some Python library as the best workaround for now.<br><br><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Sep 28, 2017 at 3:08 PM, Hermano Lustosa <span dir="ltr"><<a href="mailto:hllustosa@gmail.com" target="_blank">hllustosa@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">Ohh I see... <br><br>Just another quick question. Currently, I am creating a series of VTU and VTI files whose names follow the pattern mysimulation-t%d. With %d being replaced by an integer index identifying the time step. I am about to code a simple PVD writer to consolidate the output and also to assign the real time step value in seconds instead of maintaining this integer index.<br><br>It doesn't seem to be very hard to create this PVD file by hand, but I was just wondering if there is something in the VTK library that could automatically create these files for me. I still could not understand how I can assign the real time step in seconds to a file, don't know if its even possible with VT? files. If this is possible, some directions that could help me implement that would be very nice! <div><br></div><div>Thanks once again!<br><div><br></div><div><br><div><br></div><div><br></div></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Sep 28, 2017 at 3:50 PM, Andy Bauer <span dir="ltr"><<a href="mailto:andy.bauer@kitware.com" target="_blank">andy.bauer@kitware.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">Hi,<div><br></div><div>The TemporalStatistics filter (or any other filter that iterates through time steps) doesn't currently work with Catalyst.
