VANT. Ser.: Mat. Mod. Fiz. Proc 2011. Вып.1. С. 3-16.

Considered here are certain peculiarities of non-linear TVD-scheme application for 3D time-dependent equation of neutron transfer in curvilinear coordinates. The scheme constructed with DSn-method modification based on TVD-methodology, retains the main advantages of DSn-method: upper time layer is approximated within the counting cell, cost effective sweep method is used for difference equations. Given here are the numerical results.

Keywords: transfer equation, TVD-method, DSn-method.
