Outer Boundary Condition

It is common to have electric wall or conductor wall as outer boundary condition in electromagnetic analysis. Heat transfer:convection boundary and ambient radiation are also common when a solid in the air is analyzed.

It is troublesome to set them each time.

Therefore, the most common condition is preset to each analysis by default. It can be easily changed if necessary.

It is not allowed to set the outer boundary condition on the outer boundary once the boundary condition is set on it.

Definition of Outer Boundary

There are two types of boundaries: outer and inner boundaries. The outer boundary is the area on which just a body is bound. The inner boundary is the area where two bodies meet.

 

 

The default settings of the outer boundary condition

The default settings for each analysis are listed below.

Analysis	Boundary Condition
Electric Analysis	Magnetic wall
Magnetic Analysis	Electric wall
Thermal Analysis	Adiabatic
Stress Analysis	Free
Electromagnetic Analysis	Electric wall
Piezoelectric Analysis	Magnetic wall / Free
Acoustic Analysis	Rigid wall
Fluid Analysis	Solid wall
Simple Fluid Analysis	Wall face

 

How to Change the Outer Boundary Condition

From Menu

On the [Model] tab, go to and click [Outer Boundary Condition] .   It is selectable only when a project is open.
The [Edit Boundary Condition] dialog box will appear.

 

From Project Tree

Select [Project] tab on the Project Tree, and double click the [Outer Boundary Condition] in the [Boundary Condition].
The [Edit Boundary Condition] dialog box will appear.
