ESAIM: Mathematical Modelling and Numerical Analysis

Let 𝒬 be a partition of a polygonal domain of the plan into convexe quadrilaterals. Given a regular function , we construct a function πƒ ∈ (Ω), interpolating position values and derivatives of up of order 2 at vertices of 𝒬 . On each quadrilateral Q ∈ 𝒬 , πƒ is a finite element obtained from a polynomial scheme of FVS type by adding some rational functions.
