Continuity on Interior Boundaries
Unless a boundary condition is specified on interior boundaries (such as a contact resistance condition), the COMSOL Multiphysics software ensures continuity in the field variables across interior boundaries. For assembly geometries with identity pairs, select a
Continuity
node in the
Pairs
menu in the boundary part of the context menu for most physics interfaces. The
Continuity
condition is only suitable for pairs where the boundaries match.
Boundary Selection
The selection list in this section shows the boundaries for the selected pairs.
Pair Selection
Select the pairs where you want to impose continuity across the pair boundaries by clicking the
Add
button (
) and choose the pairs to add from the list in the
Add
dialog box that opens; then click
OK
.
