I was able to print the activation energy value for my reaction #4 using this Scheme command:
> (list-ref (list-ref (list-ref (list-ref (list-ref (list-ref (%rpgetvar 'materials) 9) 4) 1) 4) 5) 2)
2.607e+08
Here, 9=material, 4=reactions, 1=finite rate, 4=reaction #, 5=arrhenius, 2=activation energy.
Question: does anyone know the Scheme command to change that value?
Thanks.
