Details

  • This message is generated when the position of a boundary condition is not on the boundary of the region specified.
  • This problem can usually be resolved by fixing the boundary condition predicate.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[NDSolve::bcnop].

The region is given with a bound of . One DirichletCondition, however, has a predicate at that is not on the boundary of the region:

The DirichletCondition needs to be on the boundary of the region:
