cs_ale_project_displacement()

void cs_ale_project_displacement	(	const int	ialtyb[],
		const cs_real_3_t *	meshv,
		const cs_real_33_t	gradm[],
		const cs_real_3_t *	claale,
		const cs_real_33_t *	clbale,
		const cs_real_t *	dt,
		cs_real_3_t *	disp_proj
	)

Project the displacement on mesh vertices (solved on cell center).

Parameters

[in]	ialtyb	Type of boundary for ALE
[in]	meshv	Mesh velocity
[in]	gradm	Mesh velocity gradient (du_i/dx_j : gradv[][i][j])
[in]	claale	Boundary conditions A
[in]	clbale	Boundary conditions B
[in]	dt	Time step
[out]	disp_proj	Displacement projected on vertices

cs_ale_solve_mesh_velocity()

void cs_ale_solve_mesh_velocity	(	const int	iterns,
		const int	ndircl,
		const int *	impale,
		const int *	ialtyb
	)

Solve a Poisson equation on the mesh velocity in ALE framework.

It also updates the mesh displacement so that it can be used to update mass fluxes (due to mesh displacement).

Parameters

[in]	iterns	Navier-Stokes iteration number
[in]	ndircl	Number of Dirichlet BCs for mesh velocity
[in]	impale	Indicator for fixed node displacement
[in]	ialtyb	Type of boundary for ALE

cs_ale_update_mesh()

void cs_ale_update_mesh	(	const int	itrale,
		const cs_real_3_t *	xyzno0
	)

Update mesh in the ALE framework.

Parameters

[in]	itrale	number of the current ALE iteration
[in]	xyzno0	nodes coordinates of the initial mesh

cs_ale_update_mesh_quantities()

void cs_ale_update_mesh_quantities	(	cs_real_t *	min_vol,
		cs_real_t *	max_vol,
		cs_real_t *	tot_vol
	)

Compute cell and face centers of gravity, cell volumes and update bad cells.

Parameters

[out]	min_vol	Minimum cell volume
[out]	max_vol	Maximum cell volume
[out]	tot_vol	Total cell volume
