Nyatoto Guest Posts: n/a	Hi All, I want to calculate the mixing time is an agitated vessel using CFX4.4. I introduced the tracer as a pulse input, where I expect the concentration of the tracer at a monitoring point to increase with time up to a maximum, and this should mark my mixing time. However, in my case the concentration of the tracer at the monitoring point, which is far away from the input point, increases then decreases continuosly up to the end of my iterations (12,000). Where does this tracer go? regards nyatoto
