Pre-processing

The geometry simply consists of a square, representing a cavity, its top face being swept by the passing fluid. This problem is a two-dimensional case solved to illustrate the basic capabilities of Tdyn.

The best way to proceed from example 1 is to save this file with a different name. Then select again the problem type Tdyn2D (see example 1) in order to delete all the conditions of the problem.
