this allows to stop the time stepping based on
some kind of application-defined norm. e.g.
when the norm of increments between timesteps falls
below some threshold
store restart data separate from visualization data.
this has several advantages:
- no unusual striding in visualization files due to multistep methods
- we can store data which are not on a per-control-point basis
- simplify logic
- its parameters are now direct members of NonLinSIM instead. The class
SIMparameters is replaced by the new TimeStep class, which also supports
adjustable increment size and iteration cut-back. The latter is implemented
in the NonlinearDriver class of the FiniteDefElasticity application.
