	Gets the indices of the cells around a certain cell.
List< label >	ITHACAutilities::getIndices (const fvMesh &mesh, int index_row, int index_col, int layers)
	Gets the indices of the cells around a certain cell.
void	ITHACAutilities::getPointsFromPatch (fvMesh &mesh, label ind, List< vector > &points, labelList &indices)
	Get the polabel coordinates and indices from patch.
List< vector >	ITHACAutilities::displacedSegment (List< vector > x0, double mux1, double mux2, double muy1, double muy2)

Field< vector >	ITHACAutilities::rotateMesh (fvMesh &mesh, double r1, double r2, vector axis, double alpha, labelList movingPointsIDs, List< double > radii, word angleVariationMethod="Linear", double v=3)
	A function that rotates the mesh rigidly, by a fixed specified angle for the points lying within a disc of radius r1, and by a an angle which diminishes from the former angle to zero either linearly or following a Sinusoidal relation or Sigmoid function in a disc of radius r2 larger than r1.
Eigen::MatrixXd	ITHACAutilities::rotationMatrix (vector AxisOfRotation, double AngleOfRotation)
	Functions that return a Rotation Matrix given an axis of rotation and an angle in degrees.

	Compute the distance between the boundary face center and the boundary cell center.
List< label >	ITHACAutilities::getIndicesFromDisc (const fvMesh &mesh, double radius, vector origin, vector axis, List< double > &radii)
	Gets the indices of the points which are inside a disc of a specified radius before carrying out a rotation around an axis.
template<typename type_f>
List< label >	ITHACAutilities::getIndicesFromBox (GeometricField< type_f, fvPatchField, volMesh > &field, Eigen::MatrixXd Box)
