Fast Energy Barrier (FaEB) evaluation tool to assess diffusion in nanoporous materials based on Gemmi symmetrical energy grids.
Check if you have c++11 compiler installed (may work with other compiler but has been tested and mainly used with this compiler).
Tested for c++ (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0
Compilation that follows the rules set in the Makefile:
make all
./faeb structure/KAXQIL_clean_14.cif forcefield/UFF.def 298 12 Xe 0.12
You can replace the structure and forcefield files and the other parameters.
The results are printed in a comma separated (csv) format:
structure, adsorption enthalpy (kJ/mol), Henry coefficient (mol/kg/Pa), Basin energy (kJ/mol), Transition state energy (kJ/mol), Time (s)
KAXQIL_clean_14,-44.626,0.0300725,-44.3181,-25.8181,1.78605
To get Barrier energy, you simply need to substract the TS energy by the basin energy.
