A brief survey is presented of several time dependent numerical methods for multi-dimensional fluid problems in use at the Los Alamos Scientific Laboratory. Emphasis is placed on the variety of problems which can be treated, as well as on the limitations of the methods used to treat them. No details are given of the specific numerical procedures. Three examples are presented. The first, the interaction of a shock with a bubble, illustrates a type of mixed Eulerian and Lagrangian method of calculation. The second example, a shock moving down a bent channel, illustrates a pure Lagrangian calculation. The third example illustrates an incompressible fluid calculation based on a pure Eulerian method. In the second two examples comparisons are made with experimental data.
