  Please check if there is any bonded contact defined for shell bodies. If yes, please active mass scaling as sometime harmonic mass algorithm (default) gives this issue. With mass scaling, harmonic stiffness is activated which gives better energy behaviour. Please check more details in ansys help by going to below link; https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v193/exd_ag/ds_body_interactions.html
