[Paraview] [EXTERNAL] Help with 'Plot Selection Over Time' Filter

[Scott, W Alan]

Teo,
Just guessing here, but your wait time is very likely the number of files.  Plot selection over time will have to open, read, process, and close each of those files.  Try just “play” for all of the timesteps – I bet it takes numerous minutes also.  We often run problems (usually fewer timesteps, usually 10 to 1000 times bigger datasets) that take hours to run (either creating movies or plot selection over time) on some big iron clusters.

Just to make sure you aren’t running out of memory, try opening the memory inspector.  View/ Memory Inspector.  Or, open the Task Manager and look at free memory.

Alan

Subject: [EXTERNAL] [Paraview] Help with 'Plot Selection Over Time' Filter

I am having the following problem with paraview. I have a .pvd which refers to 6000-8000 .vtu files one for each time step. Each .vtu file contains information for a finite element mesh consisting of 40000-50000 nodes in 3 dimensions and contains vector values for displacement , velocity and acceleration. I load the .pvd file andi nteract with the model or watch the animation and everything is fine. The problem starts when I select a certain node and choose 'plot selection over time'  filter. The moment I press 'Apply' in the pipeline browser, paraview becomes unresponsive and I have to wait for about 5 minutes for the chart to appear. My pc has 16gb of ram and an i7 4970k cpu so I don't think that the problem is lack of resources . Am I doing something wrong? If show can you give me a hint where to look for a faster solution (a python script maybe) or is this kind of performance normal for my case?

Thank you very much.
