center of the block are significant, as shown in Figure 10; they will generate upward bending of
the block, which has an effect on the electrical solution for the modeled configuration, as will be
seen later.

The final temperature distribution for both cases is shown in Figure 11 on the deformed lining.
Note that the displacements are exaggerated for clarity. It can be seen that for the case with
shunts, most of the cathode block surface temperature is below typical start-up bath freezing
point while this is the case only at the end of the blocks for the full line load scenario.
