You could use ElementVol[] to get the surface of each 2D element (or the
length of 1D elements and the volume of 3D elements).

One way to do this would be to compute the maximum in a post-operation
(e.g. using the ternary operator "?:") and store it in a register
("Store 1"). Then use that stored value in the next post-operation
("#1") to do the normalization.
