elementSubdomainIdInList()

bool MeshTraversingUtils::elementSubdomainIdInList ( const Elem *const  elem, const std::vector< subdomain_id_type > &  subdomain_id_list  )

inline

Determines whether the given element's subdomain id is in the given subdomain_id_list.

Parameters

elem	pointer to the element to consider
subdomain_id_list	vector of subdomains to consider

normalsWithinTol()

bool MeshTraversingUtils::normalsWithinTol ( const Point &  normal_1, const Point &  normal_2, const Real  tol  )

inline

Determines whether two normal vectors are within normal_tol of each other.

Parameters

normal_1	The first normal vector to compare to normal_2.
normal_2	The second normal vector to compare to normal_1.
tol	The comparison tolerance.

Returns

A bool indicating whether 1 - dot(normal_1, normal_2) <= tol.

Definition at line 38 of file MeshTraversingUtils.h.

{
  return (1.0 - normal_1 * normal_2) <= tol;
}
