Constructor of object that holds mesh geometry data.
- Parameters
-
| [in] | index_map | Index map associated with the geometry dofmap |
| [in] | dofmap | The geometry (point) dofmap. For a cell, it gives the position in the point array of each local geometry node |
| [in] | elements | The elements that describes the cell geometry maps |
| [in] | x | The point coordinates. The shape is (num_points, 3) and the storage is row-major. |
| [in] | dim | The geometric dimension (0 < dim <= 3). |
| [in] | input_global_indices | The 'global' input index of each point, commonly from a mesh input file. |
◆ cmaps()
template<std::floating_point T>
The elements that describes the geometry maps.
- Returns
- The coordinate/geometry elements
◆ x() [1/2]
template<std::floating_point T>
Access geometry degrees-of-freedom data (non-const version).
- Returns
- The flattened row-major geometry data, where the shape is (num_points, 3)
◆ x() [2/2]
template<std::floating_point T>
Access geometry degrees-of-freedom data (const version).
- Returns
- The flattened row-major geometry data, where the shape is (num_points, 3)
