Details

  • This message is generated when the value of the indicated option is not among the expected 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::subsp].

Examples

Basic Examples  (1)

A warning is generated because E is not a valid value of the "MaxKrylovSubspaceDimension" option:

Wolfram Language code: NDSolve[{x'[t] == x[t], x[0] == 1}, x, {t, 0, 1}, Method -> {"IDA", "ImplicitSolver" -> {"GMRES", "MaxKrylovSubspaceDimension" -> E}}]

This shows a correct input:

Wolfram Language code: NDSolve[{x'[t] == x[t], x[0] == 1}, x, {t, 0, 1}, Method -> {"IDA", "ImplicitSolver" -> {"GMRES", "MaxKrylovSubspaceDimension" -> 3}}]
