Hello Foamers,

I am currently working on fluid flow in a rectangular case with electrodes placed inside (these are placed in such a way that the fluid travels in between the electrodes in zig zag manner).

I am working in 3D with steady flow and the solver used is simpleFoam. while i am simulating the iterations are been stopped at 6 and showing the error as below.

Time = 6

smoothSolver: Solving for Ux, Initial residual = 0.993905, Final residual = 0.0858968, No Iterations 9
smoothSolver: Solving for Uy, Initial residual = 0.982857, Final residual = 0.0847699, No Iterations 9
smoothSolver: Solving for Uz, Initial residual = 0.998165, Final residual = 0.0865682, No Iterations 9
