Details

  • This message is generated by a specific type of failure within the algorithms that are used for computing numerical solutions of ordinary differential equations.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[NDSolve::ndtol].

Examples

Basic Examples  (1)

The requested precision and accuracy are too high to be achieved using the default options:

Wolfram Language code: NDSolve[{x'[t] == x[t], x[0] == 1}, x, {t, 0, 1}, AccuracyGoal -> 30, PrecisionGoal -> 30]

The accuracy and precision goals specified in this example can be achieved by including a sufficiently high value for the WorkingPrecision option:

Wolfram Language code: NDSolve[{x'[t] == x[t], x[0] == 1}, x, {t, 0, 1}, AccuracyGoal -> 30, PrecisionGoal -> 30, WorkingPrecision -> 50]
