Hi every body. I have a transient problem (flow in cavity with one inlet and one outlet boundaries). I want at the end of each time step compute the avera temperature at outlet boundary and put it in the inlet boundary condition. i know the command is in the inlet boundary I just put ave(T)@outlet. But I want it at the end of time step not at the end of iteration. Yours

If you want to store data from a previous timestep, you need to use a Junction Box routine. Check the help doc.
