Functions
Real	SBMUtils::activeElementFraction (const Elem &elem, Order qrule_order, const std::function< bool(const libMesh::Point &)> &is_active)
	Compute the fraction of an element's quadrature-weighted measure satisfying a predicate.
bool	SBMUtils::isInactive (Real active_fraction, Real lambda)
	Return whether a partial element is inactive, i.e.
SubdomainID	SBMUtils::classifyPartialElement (const ElementActivity &activity, const ClassificationSubdomains &subdomains, bool mark_intercepted, Real lambda)
	Classify a (possibly partial) element into an inside/outside/intercepted subdomain.
bool	SBMUtils::checkWatertightnessFromRawElems (const std::vector< const Elem * > &bd_elements)
std::vector< const Function * >	SBMUtils::buildDistanceFunctions (const std::vector< FunctionName > &function_names, const FunctionInterface &function_provider)
	Build a list of distance functions based on names specified in input.
RealVectorValue	SBMUtils::distanceVectorFromFunction (const Function *func, const libMesh::Point &pt, Real t)
	Compute the distance vector induced by a distance function.
RealVectorValue	SBMUtils::trueNormalFromFunction (const Function *func, const libMesh::Point &pt, Real t)
	Compute the true boundary surface normal at the point on the boundary closest to pt.
RealVectorValue	SBMUtils::closestDistanceVector (const std::vector< const Function * > &funcs, const libMesh::Point &pt, Real t)
	Scan all distance functions and return the closest distance vector.
RealVectorValue	SBMUtils::closestTrueNormalVector (const std::vector< const Function * > &funcs, const libMesh::Point &pt, Real t)
	Scan all distance functions and return the corresponding normal vector.
Real	SBMUtils::unionSignedDistance (const std::vector< const Function * > &funcs, Real t, const Point &p)
	Computes the union signed distance by taking the minimum of all signed distance functions.
