Calculating particle trajectories in an specific domain

Please login with a confirmed email address before reporting spam

Hi,

I have simulated the electric potential in several low conducting media using "AC/DC" module and also used "Particle tracing" module for calculating the trajectories. Particles should move due to Dielectrophoretic force. The problem is that my particles move in a domain which has very lower potential in comparison with the other domains.

Theoretically, particles must be deflected due to the dielectrophoretic force. But trajectories are exactly the same as considering just the drag force. I think the problem is that the dielectrophoretic force in the domain which particles move in, is much smaller than the force in the other domains and this causes the computational error. I mean the solver may pass zero dielectrophoretic force.

I want to the solver just considers the domain in which particles move and evaluate the potential in this domain. How it is possible?

Bests...
