Function Documentation

cs_mesh_deform_activate()

void cs_mesh_deform_activate

(

void

)

Activate the future mesh deformation.

cs_mesh_deform_define_dirichlet_bc_zones()

void cs_mesh_deform_define_dirichlet_bc_zones	(	cs_lnum_t	n_boundary_zones,
		const int	boundary_zone_ids[]
	)

Define the boundary zones on which mesh deformation is prescribed.

Only those values at vertices matching boundary zones with prescribed displacement will really be used.

Parameters

[in]	n_boundary_zones	number of boundary zones at which to prescribe displacements
[in]	boundary_zone_ids	ids of boundary zones at which to prescribe displacements

cs_mesh_deform_finalize()

void cs_mesh_deform_finalize

(

void

)

Free structures used fo mesh deformation.

cs_mesh_deform_force_displacements()

void cs_mesh_deform_force_displacements	(	cs_lnum_t	n_vertices,
		const cs_lnum_t	vertex_ids[],
		const cs_real_3_t	displacement[]
	)

Define a fixed displacement vector for given vertices.

This displacement is enforced at all given vertices, including interior vertices.

If this function is called multiple times, the previous definitions are overwritten, so all displacements of this type must be defined in a single call to this function.

Parameters

[in]	n_vertices	number of vertices at which to prescribe displacements
[in]	vertex_ids	ids of vertices at which to prescribe displacements, or NULL if [0, ... n_vertices-1]
[in]	displacement	pointer to prescribed displacements, or NULL for no displacement

cs_mesh_deform_get_displacement()

const cs_real_3_t* cs_mesh_deform_get_displacement

(

void

)

Return pointer to current mesh displacement vector.

Returns

pointer to current displacement vector

cs_mesh_deform_is_activated()

bool cs_mesh_deform_is_activated

(

void

)

Test if mesh deformation is activated.

Returns

true if mesh deformation computation is requested, false otherwise

cs_mesh_deform_prescribe_displacement()

void cs_mesh_deform_prescribe_displacement	(	cs_lnum_t	n_vertices,
		const cs_lnum_t	vertex_ids[],
		const cs_real_3_t	displacement[]
	)

Prescribe the displacement vector for a set of vertices.

Only those values at vertices matching boundary zones with prescribed displacement will really be used, as defined by cs_mesh_deform_define_dirichlet_bc_zones.

When calling this function multiple times for different vertex sets, the most recently defined values are used for vertices belonging to multiple sets.

Parameters

[in]	n_vertices	number of vertices at which to prescribe displacements
[in]	vertex_ids	ids of vertices at which to prescribe displacements, or NULL if [0, ... n_vertices-1]
[in]	displacement	pointer to prescribed displacements

void cs_mesh_deform_solve_displacement

(

cs_domain_t *

domain

)
