◆ t8_geometry_analytic()
Constructor with analytical and jacobian functions.
- Parameters
-
[in] | dimension | The dimension of this geometry. |
[in] | name | The name to give this geometry. |
[in] | analytical | The analytical function to use for this geometry. |
[in] | jacobian | The jacobian of analytical. |
[in] | load_tree_data | The function that is used to load a tree's data. |
◆ ~ t8_geometry_analytic()
The destructor.
Clears the allocated memory.
◆ t8_geom_evaluate()
void t8_geometry_analytic::t8_geom_evaluate |
( |
t8_cmesh_t |

|
) |
| const |

virtual |
Map a point in the reference space $$[0,1]^dimension$$ to $$\mathbb R^3$$.
- Parameters
-
[in] | cmesh | The cmesh in which the point lies. |
[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. |
- Note
- Since this is the identity geometry, out_coords will be equal to ref_coords.
- Parameters
-
[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. |

Compute the jacobian of the t8_geom_evaluate map at a point in the reference space $$[0,1]^dimension$$.
- Parameters
-
[in] | cmesh | The cmesh in which the point lies. |
[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). |
- Note
- The jacobian will be (1) (1 0) (1 0 0) dim 1: J = (0) dim 2: J = (0 1) dim 3: J = (0 1 0) (0) (0 0) (0 0 1)
- Parameters
-
[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). |
Implements t8_geometry.
◆ t8_geom_load_tree_data()
Update a possible internal data buffer for per tree data.
This function is called before the first coordinates in a new tree are evaluated. You can use it for example to load the vertex coordinates of the tree into an internal buffer (as is done in the linear geometry).
- Parameters
-
[in] | cmesh | The cmesh. |
[in] | gtreeid | The global tree. |
Implements t8_geometry.
