Hi,

Here are the commands which I mean:

cell_t c;
Thread *t;
c = P_CELL(p);
t = P_CELL_THREAD(p);

Now, you can find velocity gradients in the occupied cell which is an approximation of...

How to add velocity in DPM?

Dear Freinds
I want track particles in a turbulent flow. for modeling the fluctuating velocities, I use a stochastic model which is not in FLUENT, so I should find fluctuating field, and supply...
