Details

  • This message is generated when in coupled systems DirichletCondition incidences cross-reference each other.
  • The section What Triggers the Use of the Finite Element Method explains when the finite element method is selected automatically to solve a differential equation.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[InitializeBoundaryConditions::fembdcc].

Dirichlet conditions in systems of equations cannot depend on more than one dependent variable:

If possible, remove the dependency of the Dirichlet conditions. Note that the first DirichletCondition now only depends on and no longer on :
