Detailed Description

Detect bad cells within meshes.

Please refer to the flagging of bad cells section of the theory guide for more informations.

Function Documentation

cs_mesh_bad_cells_detect()

void cs_mesh_bad_cells_detect	(	const cs_mesh_t *	mesh,
		cs_mesh_quantities_t *	mesh_quantities
	)

Compute bad cell quality indicators.

Parameters

[in]	mesh	pointer to associated mesh structure
[in,out]	mesh_quantities	pointer to associated mesh quantities structure

cs_mesh_bad_cells_get_options()

void cs_mesh_bad_cells_get_options	(	int	compute[2],
		int	visualize[2]
	)

Indicate which cell quality indicators are used and when.

Each array is optional, and returns 2 flags; the first flag is used at initialization, the second one at each time step.

A flag is a mask to be compared using an "and" (&) operation with a given criteria type mask (CS_BAD_CELL_ORTHO_NORM, CS_BAD_CELL_OFFSET, ...).

Parameters

[out]	compute	computation mask (initialization, per time step), or NULL
[out]	visualize	visualization mask (initialization, per time step), or NULL

cs_mesh_bad_cells_postprocess()

void cs_mesh_bad_cells_postprocess	(	const cs_mesh_t *	mesh,
		const cs_mesh_quantities_t *	mesh_quantities
	)

Post-process time-independent bad cell quality indicators.

Parameters

[in]	mesh	pointer to associated mesh structure
[in]	mesh_quantities	pointer to associated mesh quantities structure

cs_mesh_bad_cells_set_options()

void cs_mesh_bad_cells_set_options	(	int	type_flag_mask,
		int	compute,
		int	visualize
	)

Define which cell quality indicators are used and when.

Note

We assume that if a given criterion is computed at each time step, it is also computed at initialization, but for visualization, it is either one or the other, as visualization formats and tools may not always accept both a fixed and time-varying instance of a given variable.

Parameters

[in]	type_flag_mask	criterion type mask (0 for all)
[in]	compute	0: never compute; 1: compute at initialization; 2: compute at each time step
[in]	visualize	0: never visualize 1: visualize at initialization; 2: visualize at each time step
