# Problem Data

## Definition

Define the analysis type and other parameters required for the computation.

## Description

- Printing: The printing level (integer between 0 and 4) controls the amount of information printed in the LST file (ATILA output). It also controls the amount of information printed in the View Process Info window. The least information is obtained with 0.
- Geometry: 2D or 3D. In case of a 2D problem, define the Class which is Plane Strain, Plane Stress, or Axisymmetrical.
- Analysis: Static, Modal, Modal Resantires, Harmonic, and Transient. Modal Resantires is a special modal analysis that evaluates the resonance and antiresonance frequencies of a structure containing piezoelectric or magnetostrictive materials. Harmonic is a frequency domain computation (refer to Frequency Intervals definition). Transient is a time-domain computation.

## Illustration

## ATILA Implementation

- Refer to the ATILA documentation for more details about available analyses.
- The excitation of transient computations is defined via the boundary conditions. At the present time only transient electrical potentials are allowed.
- At this time, Plane Stress analysis is not fully implemented.
