cs_cdovb_scalsys_define()

void* cs_cdovb_scalsys_define	(	int	n_eqs,
		const cs_equation_system_param_t *	sysp,
		cs_equation_core_t **	block_factories,
		cs_cdo_system_helper_t **	p_sh
	)

Create and initialize factories for extra-diagonal blocks Build equation builders and scheme context structures for each equation which are in the extra-diagonal blocks related to a system of equations. Structures associated to diagonal blocks should be already initialized during the treatment of the classical full equations.

Case of scalar-valued CDO-Vb scheme in each block

Parameters

[in]	n_eqs	number of equations
[in]	sysp	set of parameters to specify a system of eqs
[in,out]	block_factories	array of the core members for an equation
[out]	p_sh	system helper structure to initialize

Returns

a pointer to a new allocated system context structure

cs_cdovb_scalsys_free()

void* cs_cdovb_scalsys_free	(	int	n_eqs,
		cs_equation_core_t **	blocks,
		void *	sys_context
	)

Free an array of structures (equation parameters, equation builders or scheme context) for each equation which are in the extra-diagonal blocks related to a system of equations. Structures associated to diagonal blocks are freed during the treatment of the classical full equations.

Case of scalar-valued CDO-Vb scheme in each block

Parameters

[in]	n_eqs	number of equations
[in,out]	blocks	array of the core structures for an equation
[in,out]	sys_context	pointer to a structure cast on-the-fly

cs_cdovb_scalsys_init_sharing()

void cs_cdovb_scalsys_init_sharing	(	const cs_mesh_t *	mesh,
		const cs_cdo_connect_t *	connect,
		const cs_cdo_quantities_t *	quant,
		const cs_time_step_t *	time_step
	)

Set pointers to the main shared structures.

Parameters

[in]	mesh	basic mesh structure
[in]	connect	pointer to a cs_cdo_connect_t struct.
[in]	quant	additional mesh quantities struct.
[in]	time_step	pointer to a time step structure

cs_cdovb_scalsys_solve_implicit()

void cs_cdovb_scalsys_solve_implicit	(	bool	cur2prev,
		int	n_equations,
		cs_equation_system_param_t *	sysp,
		cs_equation_core_t **	blocks,
		void *	sys_context,
		cs_cdo_system_helper_t *	sh
	)

Build and solve the linear system of equations. The number of rows in the system is equal to the number of equations. Thus there are n_eqs*n_eqs blocks in the system. Each block corresponds potentially to a scalar-valued unsteady convection/diffusion/reaction equation with a CDO-Vb scheme using an implicit time scheme.

Parameters

[in]	cur2prev	do a "current to previous" operation ?
[in]	n_equations	number of equations
[in]	sysp	set of paremeters for the system of equations
[in,out]	blocks	array of the core members for an equation
[in,out]	sys_context	pointer to a structure cast on-the-fly
[in,out]	sh	pointer to a system helper structure
