An enum controlling the behavior on detection of an invariant domain or CFL violation. Such a case might occur for either aggressive CFL numbers > 1, and/or later stages in the Runge Kutta scheme when the time step tau is prescribed.
The invariant domain violation is detected in the limiter and typically implies that the low-order update is already out of bounds. We further do a quick sanity check whether the computed step size tau_max and the prescribed step size tau are within an acceptable tolerance of about 10%.
Enumerator | |
---|---|
warn | Warn about an invariant domain violation but take no further action. |
raise_exception | Raise a Restart exception on domain violation. This exception can be caught in TimeIntegrator and various different actions (adapt CFL and retry) can be taken depending on chosen strategy. |
