<div dir="ltr">Sorry about the pre-mature end to the last message. Apparently in gmail Tab takes you directly to the send button. Here's the pseudo-code:<br><br><div><br> import paraview.simple;<br> pv = paraview.simple;<br> pv.Connect('Server');<br><br> for timestep in range(timestep_start,timestep_end):<br><br></div><div> % Do the refinement on the server<br></div><div> % Copy the parallel mesh file "dgsolution.pvtu" to "temp.pvtu", the same name what was read in by the GUI and then saved in the .pvsm file.<br><br></div><div><div> pv.servermanager.LoadState('dgsolution.pvsm');<br></div><div> pv.SetActiveView(pv.GetRenderedView());<br></div><div> pv.Render();<br></div><div> pv.SaveScreenshot('screenshot_timestep%06d' % timestep);<br><br></div><div> pv.Disconnect();<br><br></div><div> When I run the script, I get the solution at the first time step written out for each time step. So it seems that LoadState() is not re-loading the state, even though it's remote source files have changed. Another idea is that perhaps there is new view created for each time step, and I am only saving the first.<br><br><br></div><div> I'm confident I'm doing something fundamentally wrong here, I just don't know what. Also, I want to be sure that the old data is deleted at each time step, otherwise the memory requirement would be huge.<br><br></div><div>Any suggestions would be greatly appreciated.<br><br>Thank you for your time!<br><br>John<br></div><div><br><br></div><div><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Feb 18, 2015 at 6:41 PM, John Moore <span dir="ltr"><<a href="mailto:johnpmooreiv@gmail.com" target="_blank">johnpmooreiv@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"><div><div><div><div><div><div>So, this is what I would like to do, but am new to ParaView and can't figure out how to proceed.

In order to visualize the high order elements, I subdivide them Nref times, and write the data in .pvtu format. In order to save disk space, I only write the high order data at each time step.
