Abstract
In this paper, we will consider the right-hand side of a parabolic equation in a multidimensional domain, which depends only on time. For the numerical solution of the initial boundary value problem, a homogeneous implicit differential scheme is used. The problem at a particular time level is solved on the basis of a special decomposition into two standard elliptic boundary value problems. We discuss the results of numerical experiments for a model problem of filtration theory.
