Abstract: **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.
