Long time CHT transient simulation time step....
 
Hi; Im trying to simulate a stratification tank to heat storing. The key of the model is the long inertial heat terms. How i supposed to treat the time step since the heat conduction time step is much longer than the fluid time step (velocity field). how can i set up the time step to achieve a simulation of 5 or ten hours without increase the computational cost in a crazy way?

Thanks.
