2. Benchmark solution

It consists in comparing the different models, taking as reference the VISCOCHAB model integrated by RUNGE - KUTTA and a very fine step of time. Behavior VISCOCHAB is described in [R5.03.12] (explicit and implicit integration). Behavior VISC_CIN2_MEMO is described in [R5.03.04]. In particular, we will compare the maximum value of the constraints at the last cycle, as well as the variable \(q\) relating to the memory effect.
