METHODS FOR SOLVING 3-D GAS DYNAMICS EQUATIONS IN MIXED LAGRANGIAN-EULERIAN COORDINATES

V. V. Zmushko, F. A. Pletenev, V.A.Saraev, I. D. Sofronov
VANT. Ser. Metodiki i Programmy Chislennogo Resheniya Zadach Matematicheskoy Fiziki 1988. Вып.1. С. 22-27.

      Numerical calculation of 3-D equations in gas dynamics is examined. Equations are derived for mixed coordinates where some coordinate lines are Lagrangian and others are Eulerian. A difference scheme is given for a particular coordinate system with two Lagrangian and one Eulerian directions which was obtained from an original Cartesian system.
      Numerical results of 3-D perturbation evolution calculations are discussed for the Rayieigh-Taylor instabiIity.



D NONSTANTIONARY CONTINUUM MECHANICS PROBLEM CONTROL IN THE INTEGRATED SIGMA PACKAGE RUNNING IN PARALLEL ON THE ELBRUS MULTIPROCESSOR

Yu. G. Bartenev, I. V. Demin, A. I. Lukin, V. A. Saraev, I. D. Sofronov
VANT. Ser. Metodiki i Programmy Chislennogo Resheniya Zadach Matematicheskoy Fiziki 1988. Вып.1. С. 70-74.

      Vie examine the implementation of a parallel scheme for computations on the Elbrus multiprocessor using the Sigma Package.
      The multiprocessor SVS OS capabilities are extensively exploited. These include events sequencing, parent and offspring tasking, shared main and drum memory.
