      We present physical and computational models designed to simulate numerically a nonsteady-state motion of cotinuum with respect to a number of physical processes. A nonhomogeneons difference method is examined for numerical integration of a system of conservation laws. The difference shemes used are explicit. We give difference equation stability conditions and some ways for adapting spatial grids to solutions.

      We describe a general organization of the VOLNA package designed to simulate numerically a nonsteady-state motion of continuum with respect to a number of physical processes. Package architecture, input and output data, data file structure, development and operation principles are described.
