+the height of the cone, h, and ratio of base long axis length to top long axis length, r

+Note: The elliptic cone has to be truncated by planes similar to a cone or an elliptic cylinder.
+When r =1, the truncated elliptic cone becomes an elliptic cylinder.
+When r tends to zero, the truncated elliptic cone tends to a full elliptic cone.
+However, when r = 0, the top part becomes a point(tip) and meshing fails!
