The only way that I can think of is to recalculate the pe in USER_PUNCH.
The following is an example for iron. You would have to code an equation
for each redox couple.
David
SOLUTION 1
temp 10
pH 5
pe 4
Fe(2) 1
Fe(3) 1
USER_PUNCH
-heading pe_Fe(2)/Fe(3)
10 pe_fe = LA("Fe+3") - LA("Fe+2") - LK_SPECIES("Fe+3")
20 PUNCH pe_fe
