1. Reference problem

1.1. Geometry

We consider a beam of length \(1m\) oriented according to \(X\) or according to \(Z\) depending on the models.

1.2. Loads

1.2.1. Boundary conditions

In each case, node \(A\) is embedded. Then, depending on the type of moment tested, node \(B\) can either be left free or supported in a given direction.

1.2.2. Divided moments

The keywords MX, MY, MZ, MZ, MT, MFY and MFZ are applied in turn. The load is linear on the beam:

Knot	\(A\)	\(B\)
Value (N.m/m)	1000	2000

These non-constant loads are affected by the AFFE_CHAR_MECA_F command.

To test distributed moments affected by the AFFE_CHAR_MECA command, we complete this list with constant loads.
