Detailed Description

template<class TypeTag, class PhysicalModel>
class Opm::NonlinearSolver< TypeTag, PhysicalModel >

A nonlinear solver class suitable for general fully-implicit models, as well as pressure, transport and sequential models.

Constructor & Destructor Documentation

NonlinearSolver()

template<class TypeTag , class PhysicalModel >

Opm::NonlinearSolver< TypeTag, PhysicalModel >::NonlinearSolver ( const SolverParameters &  param, std::unique_ptr< PhysicalModel >  model  )

inline

Construct solver for a given model.

The model is a std::unique_ptr because the object to which model points to is not allowed to be deleted as long as the NonlinearSolver object exists.

Parameters

[in]	param	parameters controlling nonlinear process
[in,out]	model	physical simulation model.
