Implicit Boundary Assignments

If a boundary has not been assigned to a model surface, one of the following default boundaries will be assigned to the surface:

smetal	A single perfect E boundary is assigned to all objects that do not have Solve Inside selected in the Properties window and that are perfect conductors.
*i_<object name***>	A finite conductivity boundary is assigned to each object that does not have Solve Inside selected in the Properties window and that is not a perfect conductor. <object name> is the name of the object on which the boundary is assigned.
outer	A default boundary applied on the outermost surfaces of the model.

These boundary assignments are intrinsic and not displayed in the modeler.
