## D. Organization of the ATILA Supervisor

This chapter describes how to run the ATILA program using the supervisor. The example selected is an in-water harmonicanalysis of an axisymmetrical, radiating Tonpilz transducer (HAS04). Thisexample was also used in Chapter ‎III to describe the input data.

As discussed above, a computation using ATILA is carried out in 3 main steps. Each section briefly describes each step. Thefinal section presents the many options available in the ATILA supervisor.

### 1. Preprocessors

After the definition of the model (type of analysis, choiceof the elements, estimation of computation size, etc.), the mesh is generatedeither by the user or by MOSAIQUE and checked using agraphic display (Section ‎I.F).

Other currently available preprocessors consist of:

- Preflu2D/3D and Preati. The corresponding buttons on the ATILA supervisor are enabled when these modules are installed on your computer.
- GiD. The ATILA-GiD interface is launched from within GiD.

Please contact the Chairman for more information.

### 2. Computation

Using the .ati file, the problem issolved and provides files containing results and arrays for post-processing (Section G).

### 3. Exploration

The results file is analyzed in this section, through a filecontaining the results, graphic displays or animated views of the vibratingstructure. The results analysis helps the designer to understand the physicalbehavior of the problem (Section ‎H).
