Details

  • This message is generated when the value of the BandWidth option is not among the indicated forms.
  • This message applies to the BDF and IDA methods.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[NDSolve::bw].

Examples

Basic Examples  (1)

None is not a valid value of the "LinearSolveMethod" option:

Wolfram Language code: NDSolve[{x'[t] == x[t], x[0] == 1}, x, {t, 0, 1}, Method -> {"IDA", "ImplicitSolver" -> {"Newton", "LinearSolveMethod" -> {"Band", "BandWidth" -> None}}}]

This shows a correct input:

Wolfram Language code: NDSolve[{x'[t] == x[t], x[0] == 1}, x, {t, 0, 1}, Method -> {"IDA", "ImplicitSolver" -> {"Newton", "LinearSolveMethod" -> {"Band", "BandWidth" -> 2}}}]
