Details

  • This message is generated when the value of the DifferenceOrder option in NDSolve does not have the expected form.
  • DifferenceOrder is an option used within methods available to NDSolve, rather than an option to NDSolve itself.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[NDSolve::bddo].

Examples

Basic Examples  (1)

An error occurs because None is not a valid value for the DifferenceOrder option:

Wolfram Language code: NDSolve[{D[u[x, t], t] == D[u[x, t], x, x], u[x, 0] == Exp[-100 x ^ 2], u[-1, t] == u[1, t]}, u, {x, -1, 1}, {t, 2}, Method -> {"MethodOfLines", "SpatialDiscretization" -> {"TensorProductGrid", DifferenceOrder -> None}}]
