I am beginner using VASP. I try to calculate adsorption energy of CO2 on Zeolite. After the job finished the energy converged but the geometry didn't change ( geometry parameters of CO2 didn't change). Could you please tell me that job has done or not. Thank you very much in advance.

Check "reached required accuracy" in OUTCAR. Weakly adsorbed molecules sometimes exhibit no changes in geometry.

Thanks admin so much. I got it
