**v1.01.189** ZZZZ189 — Circumferential orientation using a Python loop
===========================================================================

**Summary:**

The case of a concrete hemisphere with orthoradial reinforcements under pressure in linear elasticity is treated. The aim is to orientate the frames circumferentially. This operation can be carried out in two ways.

In models :math:`(A)` and :math:`(C)`, we propose a Python function that allows this action to be carried out, by orienting the cells one by one.

In models :math:`(B)` and :math:`(D)`, we use the command AXE from option GRILLE of AFFE_CARA_ELEM, which allows a much simpler data setting of the command file to orient all the reinforcements with a single command. The results of modeling :math:`(B)` are then compared to modeling :math:`(A)`, and those of modeling :math:`(D)` to modeling :math:`(C)`.

In models :math:`(A)` and :math:`(B)`, the reference axis is :math:`(\mathrm{0,0}\mathrm{,1})`. In models :math:`(C)` and :math:`(D)`, the reference axis is :math:`(\mathrm{0,1}\mathrm{,0})`. The last two models have been added in order to have :math:`\beta` nautical angle values that are not zero.
