Detailed Description

A namespace for dealing with ODE solvers through the SUNDIALS package.

◆ LinearSolveFunction

template<typename VectorType >
 using SUNDIALS::LinearSolveFunction = typedef std::function & op, SundialsPreconditioner &prec, VectorType & x, const VectorType & b, double tol)>

Type of function objects to interface with SUNDIALS' linear solvers

This function type encapsulates the action of solving $$P^{-1}Ax=P^{-1}b$$. The LinearOperator op encapsulates the matrix vector product $$Ax$$ and the LinearOperator prec encapsulates the application of the preconditioner $$P^{-1}z$$. The user can specify function objects of this type to attach custom linear solver routines to SUNDIALS. The two LinearOperators op and prec are built internally by SUNDIALS based on user settings. The parameters are interpreted as follows:

Parameters
 [in] op A LinearOperator that applies the matrix vector product [in] prec A LinearOperator that applies the preconditioner [out] x The output solution vector [in] b The right-hand side [in] tol Tolerance for the iterative solver
Note
This variable represents a user provided callback. See there for a description of how to deal with errors and other requirements and conventions. In particular, ARKode can deal with "recoverable" errors in some circumstances, so callbacks can throw exceptions of type RecoverableUserCallbackError.
