Abstract
In this paper, a discrete analog of a conjugate-operator model preserving the structure of the original model is constructed on non-matching grids for a heat conduction problem. Numerical experiments show that the difference scheme converges with second-order accuracy for the case of discontinuous parameters of the medium in the Fourier law and non-uniform grids.
