The imbalances you speak about is referring to Global balance am i right.

You also mention Bulk quantities like pressures, velicities and temperatures have stopped changing. Correct me if i am wrong. But this would be for steady state where the above qualities stop changing.

If i am doing a transient simulation as long as the Residual target and the conservation target are met or below the target value and they stop changing after each iteration, i can consider it as converged?

I have also set monitoring points in terms of temperature.
Is there a difference for the setting for Temperature and Total Temperature? For my case of heat transfer.

Bulk quantities changing also applies to transient simulations. As the solver iterates to a solution for a given timestep it adjusts the P, V, T fields to obtain convergence. So you need to make sure these values are not changing inside the current timestep before you can declare this timestep converged and move to the next one.
