DiFfRG::TimeStepperSUNDIALS_IDA_BoostABM< VectorType, SparseMatrixType, dim, LinearSolver > Class Template Reference

A class to perform time stepping using the Boost Adams-Bashforth-Moulton method for the explicit part and SUNDIALS IDA for the implicit part. This stepper uses fixed time steps in the explicit part and adaptive time steps in the implicit part. IDA acts as the controller and the ABM stepper solves the explicit part of the problem on-demand.

Detailed Description

template<typename VectorType, typename SparseMatrixType, uint dim, template< typename, typename > typename LinearSolver>
class DiFfRG::TimeStepperSUNDIALS_IDA_BoostABM< VectorType, SparseMatrixType, dim, LinearSolver >

A class to perform time stepping using the Boost Adams-Bashforth-Moulton method for the explicit part and SUNDIALS IDA for the implicit part. This stepper uses fixed time steps in the explicit part and adaptive time steps in the implicit part. IDA acts as the controller and the ABM stepper solves the explicit part of the problem on-demand.

Template Parameters

VectorType	Type of the vector
dim	Dimension of the problem

Any derived class must implement this method to run the timestepping algorithm.

Parameters

initial_condition	A pointer to a flowing variables object that contains the initial condition.
t_start	The start time of the simulation.
t_stop	The run method will evolve the system from t_start to t_stop.
