General / Issue with ExtraFrameworkMolecule
December 17, 2020, 11:57:01 AM
Hello Prof.Dubbeldam,

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

...
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)

            ExtraFrameworkMolecule         no

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

Input files and parameters / Blocking pockets in MD?
October 16, 2019, 04:42:04 PM
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.
