2. Reference solution

2.1. Calculation method

In this test, we check that the axis nodes all have the same displacement at the end of the beam. In fact, the movement of the entire beam is rebuilt by rotating the movements of a single sector by 60°. We therefore check that the 6 coincident nodes present on the axis at z=0.1 m have the same displacement.

2.2. Reference quantities and results

The check is carried out for the first tensile compression mode and the first two flexure modes. The test is carried out on the relative displacement, which must therefore be zero.

2.3. Uncertainty about the solution

None.
