Thank you for the reply, I'll try to recompile it.

[ExtraFrameworkMolecule yes]

Hello Prof.Dubbeldam,

I am trying to make adsorption MC simulations in LTA structures but always get this error:

Code Select Expand


...
End reading cif-file
Shift all potentials
comp: 0 total: 96
Illegal instruction (core dumped)


It happens to the example code from the Tutorial as well and I found it is connected with this code line:  ExtraFrameworkMolecule         yes  (it works with No)

Any ideas how to solve this issue? RASPA generally worked well for me simulating other structures when this code line is not used.

I would suggest first to check the cif and the header of the output file (framework atoms lines) of the simulation if they state the same number of atoms in your cell. Once I used a quite large cell and amount of atoms was surprisingly reduced if compared with the input structure file.

Thank you for the information.
I am using raspa for a somewhat different than a gas in zeolite-like structures with closed pores, the system and its conditions are different to ones usually used in raspa simulations. However I found raspa as a nice code that suits my basic requirements for simple initial tests of a complicated system after some modifications of my structure with a side-pocket (as you called it). I'll think on new mods to solve my problem with MD.

Hi everyone,

I have to use blocking pockets in both MC and MD simulations. It works fine with MC, but doesn't work during MD simulations at all: gas molecules keep going inside the blocked pockets (they have open geometry in my case and are not surrounded by framework atoms). Any ideas how to solve this issue?

I will appreciate any help.
