Dear COMSOL Community,
I would like to track particles in an electric field generated by an AC electrode geometry. I have successfully gotten the particle tracking to work with a DC setup, but find the AC setup computationally burdensome. It works fine, but the solver is solving for the fields at every time step on every single cycle. This problem is only one-way coupled, I don’t expect the particles to affect the field. What I would like to do is break the problem up into two parts, first generate the AC field over 1 cycle. Next, use the 1 cycle information to apply a periodic forcing function to the particle tracking solution. There is no need to re-generate the electric field over, and over, and over again. My problem is that I am not sure how to apply the solution from the 1 cycle AC field to the particle tracking as a periodic lookup function. I figured out how to do a stationary DC field and then apply that to particle tracing (two step study), but not the same for an AC field applied as a mod(t,period) type lookup. Any suggestions or pointers to documentation would be appreciated.
Respectfully,
T.C. Lilly
