Primal finite element solution of second order problems in three-dimension space with normal stress/flux continuity

A tetrahedral finite element method of the Hermite type for solving second order elliptic equations in three-dimension bounded domains is introduced. It is a sort of extension of the Morley triangle [3] but contrary to this element it provides converging approximations in this case. The new element is particularly useful in situations where flux continuity across interelement boundaries is required.
