[OpenFOAM] pvpython: How to save several datasets at once?

TeresaT · June 7, 2019, 06:44

Hello,

I am looking for a way to safe the data of several independent filters at once using paraview.simple
I just began programming with python, so please give me a hint even though the awnser might be obviously to you.

Best regards,
Terry
-------- More explanation:
I have a set of 1000 time steps (later more) of a few cfd simulations (reader: OpenFOAmReader) and need several data written to csv files:
-plotOverLlines (at least two)
-plotSelectionOverTime (at least two, exact number unknown)

I am able two save the data one after the other but it takes a lot of time and I would like to save the data (or collect the data and save it later) without reloading every time step for every filter.

So far i use SaveData(’./interfaceVelocity.csv’, proxy=slice1_1, Precision=10, WriteTimeSteps=1) for saving

The question has been awnsered here: Paraview Forum

Short: Function will be available in paraview 5.7 and it can be done already via scripting.
