I have an unsteady flow area and would like to calculate the residence time in ParaView.
My current procedure is as follows:
- Temporal Interpolator
- point source as a plane
- use particle path filter
- use a slice filter on the Particle Path filter with a defined z-coordinate at the end of the flow area
- extract the particle age times as a csv
- creating the residence time distribution in Excel
This works for me. I have only one problem and that is, as soon as the particle moves out of the flow area, the whole particle path is deleted or disappears.
So far I have solved the problem by artificially extending the flow area with very low values for the velocity, so that the particles are still recorded.
Is there a better solution for this?
Probably there is no way to make the particles run only up to a certain z-coordinate, is there? Like similar to the Termination Time.
