Detailed Description

A class signalling a restart, thrown in HyperbolicModule::single_step and caught in the TimeIntegrator when performing a time step. We currently signal a restart whenever we encounter an invariant domain violation of the low-order update.

This might happen, for example, in subsequent invocations of step() in high-order time stepping algorithms when the time step size has to be kept constant. A standard strategy implemented in TimeIntegrator is to simply fall back to a smaller relative CFL number and try again.

The field suggested_tau_max is set to a tau_max value with which the entire update step should be restarted.
