Hello,

I would like to add an insulated boundary condition to this Parallel Plate Capacitor. I created a working model within the ES module but this module does not allow me to create an electrically insulated boundary condition. Therefore, I switched to the EC module but have not been able to obtain a result. Any advice on updating the EC module (EC_module.mph) to have an insulated boundary condition or creating an insulated boundary condition in the ES module (fringing_PPC.mph) would be appreciated.

Thanks,

Patrick

Hi Patrick,

couldn't you use dielectric shielding?

Edgar,

While Dielectric Shielding does produce the desired effect, it causes the analytical charge to stray from the calculated theoretical value, except at the smallest values of dielectric thickness which cause the boundary to act essentially as a zero charge boundary.

In 3.5 I am able to use the emqvw module to use electric insulation as intended (and the analytical value I obtain is the same as the theoretical value that I calculate if I remove the fringing field from my models). Is this same effect achievable within 4.1?

Thank you,

Patrick
