Enumeration Type Documentation

cs_grid_coarsening_t

enum cs_grid_coarsening_t

Enumerator
CS_GRID_COARSENING_DEFAULT	default among following choices
CS_GRID_COARSENING_SPD_DX	SPD, diag/extradiag ratio based
CS_GRID_COARSENING_SPD_MX	SPD, max extradiag ratio based
CS_GRID_COARSENING_SPD_PW	SPD, pairwise aggregation
CS_GRID_COARSENING_CONV_DIFF_DX	convection+diffusion, diag/extradiag ratio based

Function Documentation

cs_grid_set_diag_dom_clip_factor()

void cs_grid_set_diag_dom_clip_factor

(

double

factor

)

Set factor to ensure diagonal dominance.

Parameters

[in]

factor

clip margin factor (ignored if < 0).

cs_grid_set_matrix_tuning()

void cs_grid_set_matrix_tuning	(	cs_matrix_fill_type_t	fill_type,
		int	max_level
	)

Set matrix tuning behavior for multigrid coarse meshes.

The finest mesh (level 0) is handled by the default tuning options, so only coarser meshes are considered here.

Parameters

[in]	fill_type	associated matrix fill type
[in]	max_level	maximum level for which tuning is active
