Constructor & Destructor Documentation
◆ t8_geometry_zero()
| t8_geometry_zero::t8_geometry_zero | ( | int | dimension | ) |
Constructor of the zero geometry with a given dimension.
The geometry is viable with all tree types. This geometry maps all points to zero and is meant for debugging purposes. Sets the dimension and the name to "t8_geom_zero_{dim}"
- Parameters
-
[in] dim 0 <= dimension <= 3. The dimension.
◆ ~t8_geometry_zero()
|
virtual |
The destructor.
Clears the allocated memory.
Member Function Documentation
◆ t8_geom_evaluate()
|
virtual |
Maps points in the reference space \( [0,1]^\mathrm{dim} \to \mathbb{R}^3 \).
- 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 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] out_coords The mapped coordinates in physical space of ref_coords. The length is num_coords * 3.
- Note
- All entries in out_coords will be set to 0.
Implements t8_geometry.
◆ t8_geom_evaluate_jacobian()
|
virtual |
Compute the jacobian of the t8_geom_evaluate map at a point in the reference space \( [0,1]^\mathrm{dim} \).
- 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 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 num_coords x dimension x 3. 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 \( \frac{\partial f_j}{\partial x_i} \)).
- Note
- All entries in jacobian will be set to zero.
Implements t8_geometry.
◆ t8_geom_get_type()
|
inlinevirtual |
◆ 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.
◆ t8_geom_point_batch_inside_element()
|
inlinevirtual |
- Parameters
-
[in] forest The forest of the element. [in] ltreeid The local tree id of the element's tree [in] element The element [in] points points to check [in] num_points Number of points to check [in,out] is_inside Array to fill with flags whether the point is inside or not [in] tolerance Tolerance of the inside-check
◆ t8_geom_tree_negative_volume()
|
inlinevirtual |
Check if the currently active tree has a negative volume.
- Returns
- True (non-zero) if the currently loaded tree has a negative volume. 0 otherwise.
