In my dielectric boundary discharge (DBD) model, electrostatics module and "transport of diluted species" module are used to calculate the electric field. Then, the results provide volume force (c*es.Ex & c*es.Ey) to the laminar flow module which calculates the velocity.
I need to simulate my model for at least 50 AC cycles (1ms per cycle) to get a steady fluid flow. Since the electric field reaches the steady state in a few cycles, I am trying to find a way to save the simulation time. My basic idea is to simulate the electric field for 10 cycles ( for it to reach a quasi-steady state), and then use the results of the last cycle to CYCLICALLY calculate the fluid flow.
For example, I use the results of electric field from 9ms to 10ms to calculate the fluid flow in 9ms~10ms, 10ms~11ms, 11ms~12ms, 12ms~13ms and so on. (Variables in electric field from 0 to 9ms are used to calculate the fluid flow from 0 to 9ms)
I tried it in my model but failed. It seems that the volume force is 0 if I use previous results of electric field to calculate the fluid flow.
I really appreciate if anyone can give some comments or advice.
