Hello,

First of all, sorry for this noob question.

I have an user generated structure(CIF file). I want to dope some cation and then calculate the hydrogen storage capacity of the cation doped structure. I have prepared the following input file considering the "RASPA 2.0: Molecular Software Package for Adsorption and Diffusion in (Flexible) Nanoporous Materials" PDF file. I have a questions at this point.

Does this input file I prepared work for the purpose I intended? Or is there a fatal error?

Thank you very much for your time.

Yes, the first component is then not changing it's number of molecules, while the second component is swapped in and out.
