Description
Floating boundary conditions set the values of Fields
on a
boundary, up to an unspecified offset. Field
values on the
boundary can change, but Field
differences between two points on
the boundary will stay fixed. A separate boundary condition must
be established for each component of a Field
that is to be
constrained. Floating boundary conditions may be applied to both
Edge and
Point
boundaries.
The parameters for floating boundary conditions are the same as those for Dirichlet boundary conditions. See that discussion for details.
