t8_geom_analytic_fn

typedef void(* t8_geom_analytic_fn) (t8_cmesh_t cmesh, t8_gloidx_t gtreeid, const double *ref_coords, double out_coords[3], const void *tree_data, const void *user_data)

Definition of an analytic geometry function.

This function maps reference coordinates to physical coordinates.

Parameters

[in]	cmesh	The cmesh.
[in]	gtreeid	The global tree (of the cmesh) in which the reference point is.
[in]	ref_coords	Array of dimension many entries, specifying a point in [0,1]^dimension.
[out]	out_coords	The mapped coordinates in physical space of ref_coords.
[in]	tree_data	The data of the current tree as loaded by a t8_geom_load_tree_data_fn.
[in]	user_data	The user data pointer stored in the geometry.

t8_geom_analytic_jacobian_fn

typedef void(* t8_geom_analytic_jacobian_fn) (t8_cmesh_t cmesh, t8_gloidx_t gtreeid, const double *ref_coords, double *jacobian, const void *tree_data, const void *user_data)

Definition for the jacobian of an analytic geometry function.

Parameters

[in]	cmesh	The cmesh.
[in]	gtreeid	The global tree (of the cmesh) in which the reference point is.
[in]	ref_coords	Array of dimension many entries, specifying a point in [0,1]^dimension.
[out]	jacobian	The jacobian at ref_coords. Array of size dimension x 3. Indices 3*i, 3*i+1, 3*i+2 correspond to the i-th column of the jacobian (Entry 3*i + j is del f_j/del x_i).
[in]	tree_data	The data of the current tree as loaded by a t8_geom_load_tree_data_fn.
[in]	user_data	The user data pointer stored in the geometry.
