Temperature effects on the adsorption energy, Dmol3

Dear all,

                    Is there anyone could tell how to study the temperature effects on the adsorption energy by Dmol3?    As I know ,   when we study the adsorption energy between a small molecule and a solid surface,  we used the geometry optiminization to get the configurations of the system. 

                    However, how should we do to study the temperature effects?

Best regards
