In the help of material studio, it is writen that "The Adsorption isotherm task in Sorption calculates adsorption isotherms for a sorbate or a mixture of sorbates in a sorbent framework from a series of fixed pressure simulations at different pressures." it means that isothermal is obtained by running independent fixed pressure adsorption which starting from empty adsobent. However, I think this method is very time-consuming. it will take less time if the higher pressure starts from the previous results at lower pressure and what is more important, one can get desorption curve if the pressure goes from high to low. Is there anyway to realize the above ideal: simulate the adsorption loading at high pressure from previous simulation of low pressure. For example, after I simulate adsorption at 100 Kpa. This result (with some gas being adsorbed) is used to simulate the adsorption amount of 200 KPa, rather than run the sorption at 200 Kpa from an empty adsorbent.
