Specific functions for gradient reconstruction of the Reynolds stress tensor in the case of periodicity of rotation.

Function Documentation

cs_gradient_perio_finalize()

void cs_gradient_perio_finalize

(

void

)

Finalize gradient rotational periodicity computation API.

cs_gradient_perio_init_rij()

void cs_gradient_perio_init_rij	(	const cs_field_t *	f,
		int *	tr_dim,
		cs_real_3_t	grad[]
	)

Initialize ghost cell values for Reynolds stress tensor gradient.

We retrieve the gradient given by perinr (phyvar) for the Reynolds stress tensor in a buffer on ghost cells. then we define dpdx, dpdy and dpdz gradient (1 -> n_cells_with_ghosts).

We can't implicitly take into account rotation of a gradient of a tensor variable because we have to know all components.

We set idimtr to 2 for the Reynolds stress tensor.

We assume that is correct to treat periodicities implicitly for the other variables when reconstructing gradients.

Parameters

[in]	f	pointer to field
[out]	tr_dim	2 for tensor (Rij) in case of rotation, 0 otherwise
[in,out]	grad	gradient of field

cs_gradient_perio_init_rij_tensor()

void cs_gradient_perio_init_rij_tensor	(	int *	tr_dim,
		cs_real_63_t	grad[]
	)

We retrieve the gradient given by perinr (phyvar) for the Reynolds stress tensor in a buffer on ghost cells. then we define dpdx, dpdy and dpdz gradient (1 -> n_cells_with_ghosts).

We can't implicitly take into account rotation of a gradient of a tensor variable because we have to know all components.

(

void

cs_gradient_perio_process_rij()

void cs_gradient_perio_process_rij	(	const cs_int_t *	f_id,
		cs_real_3_t	grad[]
	)

Process grad buffers in case of rotation on Reynolds stress tensor.

We retrieve the gradient given by cs_gradient_perio_init_rij (phyvar) for the Reynolds stress tensor in a buffer on ghost cells. Then we define grad gradient (1 -> n_cells_with_ghosts).

We can't implicitly take into account rotation of a gradient of a tensor variable because we have to know all components.

We assume that is correct to treat periodicities implicitly for the other variables when reconstructing gradients.

Parameters
