Introduction:

Reduce the electrical energy consumption is important in the aluminium industry.
The electrical energy consumption of electrolysis cells is mainly due to,
 The resistivity of bath;
 The gap between the anode and aluminum-bath interface;
 The instability of this interface.
It is difficult to obtain usable measurements of the movement of the interface 960 .
Numerical methods are appropriate in having insights into thses
