2. Benchmark solution

2.1. Calculation method used for the reference solution

This problem does not have a reference solution.

Modeling A is used as a reference for modeling B.

2.2. Benchmark results

Moves \(u\) and \(v\) to points \(\mathit{P1}\), \(\mathrm{P2}\), \(\mathrm{P3}\), \(\mathrm{P4}\).

2.3. Uncertainty about the solution

The « reference » solution depends on the spatial discretization of the model; this is why the mesh is drawn in [§1.1].

Modeling B must respect this mesh to lead to the same results as A.
