Function Documentation

void t8_geometry_jacobian(t8_cmesh_t cmesh, t8_gloidx_t gtreeid, const double *ref_coords, const size_t num_coords, double *jacobian)

Evaluates the jacobian of a tree at a given reference point.

Parameters:
  • cmesh[in] The cmesh

  • gtreeid[in] The global id of the tree

  • ref_coords[in] The reference coordinates at which to evaluate the jacobian

  • num_coords[in] The number of reference coordinates

  • jacobian[out] The jacobian at the reference coordinates
