Some simple questions about AC DC module

Dear all,
Recently I need to do some simulation with AC/DC module. I use a lot RF module, but not really familiar with AC/DC module. I have several simple questions related.
1. Is it possible to specify global electric potential (mimicking a homogeneous electric field) to polarize a finite object? (A bit similar to solving for the scattered filed in RF module)
2. Is complex permittivity allowed in AC/DC module?
3. What's the boundary condition to terminate an open space surrounding an object?
Thanks in advance!

hello
For static and quasi-static(AC-DC module ) models, it is possible to assume zero fields at the open boundary, provided that this is at a sufficient distance away from the sources. because in low frequency radiation effect can be assumed neglected .
about question 2:
when you define a material with specific sigma(conductivity)and permitivity(epsilonr)that is equal to material with zero conductivity and complex permitivity

Pu,
To terminate an open space, use Infinite Element Domain feature under Definitions.
