Operands
=========

**Reminder:**

The recombination of FOURIER on the trips is written as:

:math:`u(\theta )\mathrm{=}\mathrm{\sum }_{l\mathrm{=}0}^{N}\left[\underset{{A}^{s}}{\underset{\underbrace{}}{(\begin{array}{ccc}\mathrm{cos}l\theta & 0& 0\\ 0& \mathrm{cos}l\theta & 0\\ 0& 0& \mathrm{-}\mathrm{sin}l\theta \end{array})}}{u}_{l}^{s}+\underset{{A}^{a}}{\underset{\underbrace{}}{(\begin{array}{ccc}\mathrm{sin}l\theta & 0& 0\\ 0& \mathrm{sin}l\theta & 0\\ 0& 0& \mathrm{cos}l\theta \end{array})}}{u}_{l}^{a}\right]`

A symmetric harmonic is therefore recombined with the matrix :math:`{A}^{s}`, an antisymmetric harmonic with the matrix :math:`{A}^{a}`.

The recombination of FOURIER on deformations and stresses is written as:

:math:`\varepsilon (\theta )\mathrm{=}\mathrm{\sum }_{l\mathrm{=}0}^{N}(\left[\begin{array}{cc}\mathrm{cos}l\theta {I}_{4}& {0}_{\mathrm{4,2}}\\ {0}_{\mathrm{2,4}}& \mathrm{-}\mathrm{sin}l\theta {I}_{2}\end{array}\right]{\varepsilon }_{l}^{s}+\left[\begin{array}{cc}\mathrm{sin}l\theta {I}_{4}& {0}_{\mathrm{4,2}}\\ {0}_{\mathrm{2,4}}& \mathrm{cos}l\theta {I}_{2}\end{array}\right]{\varepsilon }_{l}^{a})`


Operand RESULTAT

    ♦ NOM_CHAM = symb name,

Symbolic name of the recombined field (s).


Operand ANGLE
