Template Function grid_element_to_coords

Function Documentation

template<typename grid_t>
void grid_element_to_coords(const grid_t grid, const t8_locidx_t itree, const t8_element_t *element, const int curved_flag, double *coordinates, const int num_node, const t8_element_shape_t shape)

Compute the coordinates of the corners of an element in the grid.

If the grid is a forest the input for element is ignored.

Template Parameters:

grid_t –

Parameters:

  • grid – [in] The forest/cmesh to use.

  • itree – [in] The local id of a tree in grid.

  • element – [in] An element in the tree with local id itree. If grid is cmesh the input is ignored.

  • curved_flag – [in] If true, we use quadratic elements to write.

  • coordinates – [inout] An array with enough space to hold 3*num_node doubles. On output filled with the coordinate of the corners of the element/tree

  • num_node – [in] The number of nodes to use to describe the element/tree.

  • shape – [in] The shape of the element/tree.
