If a quadratic quadrilateral element has an additional node at the
element center, it is a bi-quadratic element (or
QUAD9). If a quadratic hexahedral element has 7 additional nodes:
-at the element center and at the center of each side it is a
+at the element center and at the center of each side, it is a
tri-quadratic element (or HEXA27).
