What is the k in electrostaticFoam

Hi

what is k in electrostaticFoam? it seems like conductivity from the eqution. but not in unit?
is it something like p(pressure/rho) in simplefoam.???

thanks

Hello @waynezw0618, did you ever find an answer to your question? I'm currently reading through the solver as well and haven't yet been able to determine what the meaning of this constant is.

For what it's worth, the units are $\frac{s^2 A}{kg}$

Dear Somorjai,
Thank you for your reply. But I still cannot understand . I think k should not be electrostatic constant because of different units. It has an unit of electrical conductivity / charge density.
