Disconnected Solution Domains

There are two ways to create a problem that contains multiple disconnected solution domains:

• By not creating or by excluding (not solving in) the background object, when the included objects are not all touching.
• By using excluded objects or perfect conductors that cut the included objects into different regions.

The Maxwell solver identifies multiple disconnected solution domains.

For the electric solvers (electrostatic, conduction, and conduction+electrostatic), the solution is allowed even if multiple disconnected solution domains are detected. In this case, an error message appears only if a solution domain with inconsistent or unsolvable solution setup is detected.

For the magnetic solvers (magnetostatic, eddy current, and transient EM), an error message appears when multiple disconnected solution domains are detected.
