Numerical results show that first-order Lagrange polynomials are the optimal mapping procedure for the one-dimensional problem and second-order Lagrange polynomials, for the two-dimensional one.journal articlehttp://www.sciencedirect.com/science/article/pii/S0021999184710771http://www.sciencedirect.com/metadata only access53004Física (Física)Informática (Informática)22 Física1203.17 Informática
