EXSIE is called at every cycle for every element.

Basically, you only need to enter DSIE so program will read DSIE and then deposit it to the element which calls the EXSIE. 

If each element has different value of DSIE, you can add IF-THEN statements in EXSIE to calculate the DSIE for the specified element (I = INOW, J = JNOW, K = KNOW).

Density, Pressure, etc, will be calculated outside of EXSIE by other subroutines.
