Domain and Boundary Nodes for the Wall Distance Interface
The Wall Distance Interface
has these domain settings and boundary conditions available:
•
Distance Equation
•
Initial Values
•
Periodic Condition
•
Wall
•
Wall Distance Continuity
The default boundary condition, a homogeneous Neumann condition, applies to all boundaries that are not walls:
This node does not display in the model tree.
For axisymmetric models, COMSOL Multiphysics
automatically takes the axial symmetry boundaries (at
r
=
0
) into account, and prohibits the wall boundary node from being defined here.
