The solution of a hybrid finite element method (HFEM) problem is considered. It is shown that suitable ordering of the FEM mesh results in a canonical HFEM matrix system. This linear system can be solved in O(N1.5) cost when the sparse methods are used. Proposed in this paper is the ordering of the FEM mesh which results in a canonical matrix system. In order to distinguish this ordered form of HFEM from a straightforward HFEM, this technique is called ordered hybrid finite element method (OHFEM).
