I ran a simulation of a polymeric solution inside an extrusion die by using laminar flow and carreau model. Afterwards, I implemented the particle tracing module, beacuse I am interested in the residence time which is the time a particle takes to exit the die.
Does anybody know how to add the auxiliary dependent variable: d(rp)/dt = 1 in the particle tracing module?
Somebody told me that this will solve the additional ODE per particle, and rp is the residence time.
