Abstract: | An algorithm for constructing completely conservative difference scheme forkyperbolic differential equations in two dimensions is presented. Using a differencescheme with parameters for two-dimensional Eulerian hydrodynamic equations, it isshown that the parameters have to satisfy some conditions if the completely con-servative difference schemes are to be constructed. |
