Typedef Documentation

t8_geom_analytic_fn

typedef void(* t8_geom_analytic_fn) (t8_cmesh_t cmesh, t8_gloidx_t gtreeid, const double *ref_coords, const size_t num_coords, double *out_coords, 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 x num_coords many entries, specifying a point in \( [0,1]^\mathrm{dim} \).
[in]	num_coords
[out]	out_coords	The mapped coordinates in physical space of ref_coords. The length is num_coords * 3.
[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, const size_t num_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 x num_coords many entries, specifying points in \( [0,1]^\mathrm{dim} \).
[in]	num_coords	Amount of points of /f$ \mathrm{dim} /f$ to map.
[out]	jacobian	The jacobian at ref_coords. Array of size \( \mathrm{dim} \cdot 3 \) x num_coords. Indices \( 3 \cdot i\) , \( 3 \cdot i+1 \) , \( 3 \cdot i+2 \) correspond to the \( i \)-th column of the jacobian (Entry \( 3 \cdot i + j \) is \( \frac{\partial f_j}{\partial x_i} \)).
[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.
