calculation of certain parameters using PV filter for all the snapshots(dump file)

[deepakpawar2310 (Deepak K Pawar)]

(1) I need to calculate specific parameters using the PV filter (external ) to a particular snapshot
(dump file),

(2) store that variable, and

(3) use the same filter for subsequent snapshots (for example, I have 400 snapshots/dump data).
Are there any inbuilt commands or functions for this?

Similarly, I have over 500 dump files. As a result, I’m not sure how to execute it in one approach.

Any help/comments will be highly appreciated!

Thank you

Use a python script ?

[deepakpawar2310 (Deepak K Pawar)]

Yes, it appears to be doable.
(1) How python script will load the vtk file automatically

(2) After that, it will most likely be necessary to run the PV filter and save the variable.

(3) Then need to upload the following vtk file

(4) After that, repeat the procedure with the next vtk file.
1-2-3

And how can run the python script to accomplish the task above?
I’m using Ubuntu 16.04

OpenDataFile()

(2) After that, it will most likely be necessary to run the PV filter and save the variable.

YourFilter()

(3) Then need to upload the following vtk file

SaveData()?

(4) After that, repeat the procedure with the next vtk file.

for loop ?

You can try using the python trace to understand how to write a pvpython script

One good resource is the Sandia tutorials, located here: https://www.paraview.org/Wiki/SNL_ParaView_Tutorials. You want to go through the Paraview and Python, and the PvPython and PvBatch tutorials.
