Hi,

I'm trying to simulate a simple EHD flow with CFX: it's a 2D channel flow with the top wall at an eletric potential +V and the bottom wall at -V. My fluid contains anion and cation and I want to see how their spatial distributions are affected by the electric potential.

I got an example from the customer portal with charged particles. However, this is for discrete spatial distribution (ie charged particles). Whereas I need the charge density to be determined from my anion/cation concentrations.

Is it possible to do this with CFX12.0? If so, how do I implement the continuous distribution for the charge density?

Thanks,

Charlotte
