PSD of Zeolitic systems with mobile cations
« on: November 26, 2021, 07:06:10 PM »
Dear RASPA community,

I wonder if anyone has attempted to compute PSD for a porous framework with mobile cations (e.g. cation-exchanged zeolites)?
I have tried to do this for NaY zeolite with mobile Na cations. I have successfully set up a MC simulation that runs perfectly and computes PSD at every few steps (please see an example of my input file below ).

However, I wonder if RASPA takes into account mobility of cations in its calculation of the PSD in such cases? (i.e. PSD must be slightly different every time that cations move around and be averaged at the end).

My input file:
