	Funding: Work supported by the US DOE under contract DE-AC02-76SF00515. ACE3P is a 3D parallel finite element code suite for cavity design and optimization including electromagnetic, thermal and mechanical effects. Taking advantages of the power of computing on multi processors, ACE3P's particle tracking module Track3P allows efficient multipacting (MP) simulation by extensive scanning in field gradient and on cavity surface to identify the occurrences of MP activities. The output from Track3P simulation includes the determination of resonant trajectories and their locations, the calculation of electron impact energy on cavity surface, and the evaluation of the electron enhancement counter as a function of field gradient. The sensitivity of MP on secondary emission yield can be readily obtained through postprocessing. Examples of Track3P MP simulation for the Muon cooling cavities and APS SPX cavity will be presented.
