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
