Dear Foamers,

I am solving a transport equation governed by diffusion and electrostatic interactions. As I increase my input parameter, I see a large electrostatic interaction resulting in irregular noise in my output. I would like to ensure there is no numerical artifacts in these results.

1. I would like to know how much does the relaxation factor play a role in ensuring the results are physical.

2. What could be other tests other than grid tests, to ensure solver is accurate.

Kindly let me know

Thanks

Regards
