what does zig-zag pathline mean

Dear All,

I get zig-zag pathlines. They jump up and down very often. What do the jumps mean? Do they mean there are recirculation near this area? Thanks all.

create a slice in the middle of your domain and check velocity distribution and also pressure distribution (on this slice)

If you've turned on the stochastic tracking found in the turbulent dispersion tab of the injections dialog, the jitter in pathlines could be due to the interaction of your particles/fluid elements with local turbulence.
