2. Benchmark solution

2.1. Calculation method used for the reference solution

Modeling A (2 DD_PLAN) is used as a reference for shell models.

2.2. Benchmark results

Moves following \(\mathrm{Ox}\) and \(\mathrm{Oy}\) from point \(X\) to \(\mathrm{mm}\).

2.3. Uncertainty about the solution

Experience shows that if you double the number of elements in both directions, the result varies by less than 2%.

The convergence criteria chosen must also make it possible to achieve the precision estimated for this 2D calculation: (2 or 3%).
