HyperView Coordinate Systems
In the Contour, Iso Value, Tensor Plot, Vector Plot, and Deformed panels, you can select the result coordinate system to be used to process results.
Subsequent options are dependent on the current averaging method. The available coordinate systems are:
Global
The HyperView default coordinate system. It is displayed in the bottom left corner of the HyperView modeling window.Element
Defined from the geometry, that is, the nodal connectivity of the element. The HyperView element coordinate systems for the following elements are described: Quad4/Quad8
 For Quad elements, the reader automatically selects one of the following methods:
 The origin of the coordinate system is located at the centroid of the element.
 x is along a line that bisects the angles between G2G4 and G1G3.
 y is perpendicular to x as shown in the figure.
 The origin of the coordinate system is located at the centroid of the element.
 x is along the G1G2 line.
 y is perpendicular to x.
 Tria3/Tria6

 The origin of the coordinate system is located at the centroid of the element.
 x is along the G1G2 line.
 y is perpendicular to x as shown in the figure.
 Hexa8/Hexa20
 The element coordinate system for the Hexa element is defined in terms of the three
vectors R, S, and T, which join the centroids of opposite faces, as follows:
 R vector joins the centroids of faces G4G1G5G8 and G3G2G6G7.
 S vector joins the centroids of faces G1G2G6G5 and G4G3G7G8.
 T vector joins the centroids of faces G1G2G3G4 and G5G6G7G8.
The origin of the coordinate system is located at the centroid of the element. The axes are derived as follows: z = T
 y = T x R
 x = y x z
 Tetra
 The element coordinate system is derived from the three vectors, R, S, and T, which
join the midpoints of opposite edges, as follows:
 R vector joins midpoints of edges G1G2 and G3G4.
 S vector joins midpoints of edges G1G3 and G2G4.
 T vector joins midpoints of edges G1G4 and G2G3.
The origin of the coordinate system is located at the centroid of the element. The axes are derived as follows: z = T
 y = T x R
 x = y x z
 Penta
 The element coordinate system for the Penta element is derived accordingly. A midplane
is formed by the three midpoints of the straight lines between the top (G1G2G3) and
bottom (G4G5G6) triangular faces. The origin of the coordinate system is located at
the centroid of the element. The axes are formed as follows:
 z = A line along the bisector of the midplane normal and the line connecting the centroids of the top (G1G2G3) and bottom (G4G5G6) faces.
 y = The vector connecting points P and Q where P and Q are defined as
follows:
P = The midpoint along the line, G1G4. In order to define Q, you must define a plane that passes through P and is perpendicular to axis z.
Q = The intersection of the plane defined above and the line G3G6.  x = The intersection of the plane defined above and the line G3G6.
