Function Documentation

cleanup_solver()

void cvode::cleanup_solver

(

int

num_threads

)

Cleans up the created solvers.

Parameters

num_threads

The number of OpenMP threads used

Frees and cleans up allocated CVODE memory.

Definition at line 165 of file cvodes_init.c.

init_solver_log()

void cvode::init_solver_log

(

)

Definition at line 190 of file cvodes_init.c.

initialize_solver()

void cvode::initialize_solver

(

int

num_threads

)

Initializes the solver.

Parameters

num_threads

The number of OpenMP threads to use

Various definitions in the generated options, e.g. FINITE_DIFFERENCE, CV_MAX_ERRTEST_FAILS, etc. affect the options set for the CVODEs solver.

See also

solver_options.h

The RHS function dydt_cvodes() will be used in the solver.

If FINITE_DIFFERENCE is not defined, the jacobian function in eval_jacob_cvodes will be used in the CVODE solver. Else, the CVODE finite difference based on the RHS function will be used.

intDriver()

void cvode::intDriver	(	const int	NUM,
		const double	t,
		const double	t_end,
		const double *	pr_global,
		double *	y_global
	)

Integration driver for the CPU integrators.

Parameters

[in]	NUM	the number of IVPs to solve
[in]	t	the current IVP time
[in]	t_end	the time to integrate the IVP to
[in]	pr_global	the pressure value for the IVPs
[in,out]	y_global	the state vectors
