class MoreauJeanCombinedProjectionOSI : public MoreauJeanOSI
#include <MoreauJeanCombinedProjectionOSI.hpp>

One Step time Integrator for First Order Dynamical Systems for mechanical Systems (LagrangianDS and NewtonEulerDS) with Combined Projection Algorithm.

This class reimplement a special activation of constraints in the MoreauJeanOSI for the Combined Projection Algorithm
