template<class T1>
class SIMSolver< T1 >

Template class for transient simulator drivers.

This template can be instantiated over any type implementing the ISolver interface. It provides a time stepping loop and restart in addition.

Member Function Documentation

◆ deSerialize()

template<class T1 >

virtual bool SIMSolver< T1 >::deSerialize ( const HDF5Restart::SerializeData & data )
