2. Benchmark solution#

2.1. Calculation method used for the reference solution#

The reference results were obtained with Europlexus.

The meshes used by Europlexus and Code_Aster are the same.

2.2. Benchmark results#

The reference results correspond to the following displacement \(Z\) of the node \(\mathit{N9}\) located in the center of the beam. They were obtained at moment \(t\mathrm{=}\mathrm{0.001s}\).
