  3. My solver run stops with the message ‘RMS res. and GLOBAL imbalances are below their target criteria’, yet the imbalances on some variables are still large. How do I ensure that the solver only stops when a tight convergence is achieved?

      On the Solver Control form/Basic Settings/Convergence Criteria, tick the box ‘Conservation Target’ and set the imbalance target that you want to achieve (a value of 0.01 stands for a 1% imbalance). If this is not ticked, the convergence control is only done on the residuals.
