Ideal efficiency is one iteration per I <br />time step. Altering the underrelaxation pa cameter, I <br />lowering the time step, increasing Ue flow antl head I <br />tolerance are gootl ways of improving the efficiency, I <br />another is lowering the internal time step. The lower thel <br />efficiency generally the 'faster your model will run. I <br />If your ef£ic iency is less than I.5 then you may txy I <br />increasing your time step so that your overall simulation) <br />is faster.
