I’m trying to plot pressure as a function of time for tracers in an spcth file.
The data pipeline is set up as follows:
spcth -> Volume Data (extract cells’ Pressure) -> Merge Blocks -> CellDataToPointData -> PlotSelectionOverTime (PSOT)
I activate the tracer points by displaying them in the render window, and use “Select Points On (d)” to draw a box around the tracers of interest. The points are then highlighted in pink. When I advance time forward, the updated tracer locations are still highlighted.
In the PSOT properties, I toggle “only report selection statistics” off, and then push apply. After a few moments, some plots of pressure vs time are generated, but these plots are very different from the plots I generate from the hscth csv file. The attribute type is also set to “row data.” The other attributes are blank.
I think I discovered the underlying problem by looking at the PSOT in spreadsheet mode: all the points in the point coordinate column were set (seemingly arbitrarily) to 0 0 -2, and not any of the tracer values (which I can also monitor in a separate spreadsheet pane). To further troubleshoot, I used a probe location filter to select the point 0 0 -2 and then generated a PSOT of that point. The same, incorrect pressure vs. time plot was generated. The tracer points move as a function of time, but I need the pressure at those time-varying points, so I can’t just simply pick a static point and plot its pressure.
Is there a way to plot the pressure at these time varying points over time in Paraview?
Static mesh, spread over 8 blocks
I’ve been able to render all relevant geometries in 3D and using the slice filter. I can also plot pressure over a line.
Please let me know if additional info is needed.
