The pressure profile is chosen by setting the switch in the input file. The value of the pressure on axis is give by in units of . Thus if then the value of on axis = . In some cases it is necessary to rerun the equilibrium code to get a precise desired value after the normalization is determined.
IFUNC = 1 - Standard PEST profile.
IFUNC2 = 4 - TEQ profile.
In this option the pressure profile is obtained by interpolation from an array, which is read from a file, . As before is set independently to fix on axis.
