v2.08.011 FORMA11 - Practical work from the « Dynamic Analysis » training course: modal analysis

Summary:

These tests correspond to the practical work of the dynamic training of*Code_Aster*. These are four geometries, all made up of a linear elastic material for which a modal analysis is carried out: search for natural frequencies and associated modes.

The models used are as follows:

• Modeling A: Searching for multiple modes of a beam (POU_D_E)

• B modeling: Search for rigid body modes of a sphere (3D)

• Modeling C: Use of operator CALC_MODES for the analysis of a cooling tower (DKT),

The statements of the practical work of dynamic training are presented in this document:

• TP1: Searches for multiple modes of a beam,

• TP2: Look for rigid body modes,

• TP3: Using the CALC_MODES macro command.
