In this paper we extend the idea of interpolated coefficients for a semilinear
problem to the quadratic triangular finite volume element method. At first we introduce
quadratic triangular finite volume element method with interpolated coefficients
for a boundary value problem of semilinear elliptic equation. Next we derive convergence
estimate in H1
-norm and L
∞-norm, respectively. Finally an example is
given to illustrate the effectiveness of the proposed method.
