Enumeration Type Documentation

IDViolationStrategy

enum class ryujin::IDViolationStrategy

strong

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.

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.
