摘要：
There exists tough convergence, burden computation, and low efficiency for solution to partial difference equations using Velocity-Verlet or ODE algorithms analyzing characteristics of particle motion. The finite element software COMSOL Multiphysics 5.3a, which could be used to solve Laplace equation quickly in AC/DC module when these reasonable boundaries were chosen, provides the precondition for calculating dielectrophoretic force. In terms of particle tracing module in COMSOL software, the particles experienced dielectrophoretic effect were simulated through the selection of both time step and range when dielectrophoretic, Stokes drag, repulsive, and buoyant forces were taken into the table of stress parameter in particle tracking module. The results illustrated that this approach is capable of simulating the motion of such particles exerted by dielectrophoresis effect, reducing the complexity of program and improving man-machine visualization of dynamic simulation, and are consistent with Velocity-Verlet or ODE algorithms. © 2021, Editorial Department of Journal of Northeastern University.
