    Details

    • This message is generated in case a DirichletCondition is nonlinear.
    • Nonlinear Dirichlet boundary conditions are not supported in this version.
    • Off[message] switches off the message; On[message] switches it on. For example: Off[InitializeBoundaryConditions::fembdnl].

    Examples

    Basic Examples  (2)

    The given Dirichlet boundary condition is nonlinear:

    Wolfram Language code: NDSolve[{Laplacian[u[x, y], {x, y}] == 1, DirichletCondition[Sin[u[x, y]] == 0, True]}, {u}, {x, y}∈Rectangle[]]

    This message can be generated by other functions:

    Wolfram Language code: Needs["NDSolve`FEM`"] vd = NDSolve`VariableData[{"DependentVariables", "Space"} -> {{u}, {x, y}}]; sd = NDSolve`SolutionData[{"Space"} -> {ToElementMesh[Rectangle[]]}];
    Wolfram Language code: InitializeBoundaryConditions[vd, sd, {{DirichletCondition[u[x, y] ^ 2 == 0, True]}}]
