Abstract
A triangular composite element with 15 degrees of freedom is introduced. It is shown that after an appropriate modification of the Zlámal coordinate transformation this element can be employed as a reference element to curvilinear triangular element of class C with nine degrees of freedom. A complete list of the basis functions, together with a procedure for their automatic generation are included.
