Descrição

In this paper we study convergence of numerical discretizations of hyperbolic nonhomogeneous scalar conservation laws. Particular attention is devoted to point source problems. Standard numerical methods, obtained by a direct discretization of the differential form, fail to converge, even in the linear case. We consider the equation in integral form in order to construct a class of convergent accurate methods. Numerical examples are included. http://www.sciencedirect.com/science/article/B6TYH-3YMFK8J-R/1/cbe49d4b91208a476f2e65596d793511
