Default Periodicity in time
Posts: n/a
When the fluid flow solution of a simulation is periodic in time and you want to simulate the passage of particles through this flow it is sometimes very computationally expensive to use the discrete particle model in transient mode. This will mean that when the particles reside in the domain for a much longer time than the period of your flow that you have to calculate the same solution over and over again.

Is there a way in Fluent to circumvent this so that one only has to calculate one period and then use these results to follow the motion of particles? I'm thinking maybe to write the data files and then write some "execute commands" script to read them back in. Does anybody have experience with this?

Kind regards
