Plotting contour length over time steps

Hello,
I'm doing multiphase simulations and analyzing data in Paraview 5.9. I'm using the following tree : -Slice -Reflect -Contour -Integrate Variables This tree can give me the contour length at a given time step. Would it be possible to plot this contour length over time ? Or at least get a column file with contour length for all time steps ? If it can't be done easily in Paraview, can it be done in openFoam with some functions ? Edit : OK, I have found the filter plot data over time where contour length should be available. Only problem is that it takes a lot of memory and you can't chose the data before processing all time steps... Edit 2 : OK, processing time steps takes huge loads of memory but I can process through 2000 time steps in like an hour or so, so it's doable. Will be much longer for million cell meshes... Edit 3 : To get your data in a line/column file : -Contour -Integrate variables -Plot data over time (cell data) -Extract time steps And then just export the spreadsheet Last edited by Rotidpor; August 4, 2022 at 08:55. Reason: Dumb questions, just search in the filter list... |
