Dear Prof. Dubbeldam and RASPA community,
When calculating the adsorption of propylene in MOF, I set the porosity in the input file. However, why are the values for absolute and excess adsorption still the same when helium porosity is set?
Below is my input file.
Best Regards!

The values are not the same. Excess is slightly smaller.
In the limit of low pressure, excess and absolute adsorption become equal. They start to deviate at high pressures.
