- This message is generated when the indicated number of refinements of the range of integration is not sufficient to achieve the requested accuracy.
- This message can be generated when NIntegrate is used with Method->DoubleExponential or Method->Trapezoidal.
- Difficulties with convergence of a numerical integral can sometimes be addressed by using a different value of the Method option, decreasing the value of the PrecisionGoal or AccuracyGoal option, increasing the value of the MaxRecursion option, or transforming the integral to a form that can be handled more easily.
- Off[message] switches off the message; On[message] switches it on. For example: Off[NIntegrate::ncvi].
