Example12 Periodic Boundary Condition

General

• The unit capacitors, consisting of alumina blocks and electrodes, are periodically placed in the analysis space.
   

• By applying periodic boundary conditions, the analysis area can be minimized.
   

• The distributions of electric field and potential are solved.
   

• Unless specified in the list below, the default conditions will be applied.
   

Analysis Space

Analysis Conditions

Select “Static analysis” as the potential is static.

Create the ambient air manually. Deselect the automatic creation.

Model

The base unit of the periodic structure is modeled.

Body Attributes and Materials

* Available from the Material DB

Boundary Conditions

On the [Model] tab,

click [Boundary Pair] and complete the pairing as follows.

Results

The vectors of the electric field are shown below.

The isoline contour of the potential is shown below.

The paired faces of the periodic boundary conditions have the same values,

which proves that the solution is correct.

For comparison, the potential is calculated under the magnetic wall boundary condition.

The resulting isoline contour is shown below.
