Particle trace in CONVERGE

hosseinamir71 · September 4, 2017, 13:52

Hello
I want to track some particles which I used as a spray drops in CONVERGE. The thing is that every time I tried to use to get he pathline or streamline, I could not and instead, it switches to the NODE TRACK type and I could not change it.
Does anyone know why this happens and how I can fix that. Thanks

Hi,

Unfortunately CONVERGE doens't assign an ID to the particle in the Measured/Particle data part, so there is no way for a post-processor to be able to track a single particle along its evolution.
You can create particle traces (streamline / pathlines), but these show the evolution of a particle inside the fluid domain - that's not the same as tracking one of the Measured/Particle droplet.

Sorry there isn't a real answer this time. I hope this clarifies what is happening.
