Simple electric potential model
 

Hello everybody,

I have problem with setting electric-isolation (specified flux=0) BC on interface between solid and fluid zone.

This interface is Two-Sided Wall and I need to apply insulation on PART of it (look the attachment) to direct electric current to pass through unisolated part of interface.

Wall and its shadow-pair do not offer potential BC for interface (look the attachment).

Any suggestions? UDF? Thanks :) :)

It seems possible to solve this problem by defining UDS in Fluent. I did some testing and Fluent enables defining different UDS boundary conditions on interior boundaries.
