1. But

Fourier analysis is intended to calculate the response of structures with axisymmetric geometry stressed by non-axisymmetric loads broken down into Fourier series.

Limitations:

• the decomposition of the load into Fourier series is assumed to have been done by the user,

• Aster implantation only concerns isotropic or orthotropic materials,

• in thermics, there is no global control that can solve a problem on several harmonics. The calculation must be done harmonic by harmonic.
