Member Function Documentation
◆ t8_geom_evaluate()
|
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
- All entries in out_coords will be set to 0.
- 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.
Implements t8_geometry.
◆ t8_geom_evalute_jacobian()
|
virtual |
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
- All entries in jacobian will be set to zero.
- Parameters

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()
|
inlinevirtual |
Update a possible internal data buffer for per tree data.
This function is called before the first coordinates in a new tree are evaluated. In this implementation, we do nothing, since we do not need any tree data.
- Parameters
-
[in] cmesh The cmesh. [in] gtreeid The global tree.
Implements t8_geometry.
