su1.04.01 User manual for modeling and calculating pipes

Summary

This document aims to help the user create a pipe line with Salome-Meca, consisting mainly of pipe, elbow and tee elements, and to perform a pipe calculation with Code_Aster.

A specific development has been carried out in order to be able to simply create and connect 3D elbow-type elements at the intersections of wire lines.
