Hello everyone!

I want to measure the time it takes for a flow particle to reach to the surface of the blades of Impeller starting from a specific spot in the domain...in order to do that, I did particle tracking with massless particles, but what the results of particle tracks show, is not the one that I expect based on the pathline visualization. Does anyone know what the best type of injection is for this case. the fluid is trapped inside a closed area of the tank and there is no initial movement before the impeller start rotating...
any ideas and suggestion is welcome and appreciated...
Thank you,
Sahar
