Reply To: Simulation giving out: absoluteErrorL2(line)=0.0981649 and relativeErrorL2(line)

I mean by the message that, the Cavity2D example is in Laminar Form and I want to change it in Turbulent Form and so I made some changes in the code:

1st Change:
using T = FLOATING_POINT_TYPE;
using DESCRIPTOR = D2Q9<>;
using BulkDynamics = ConstRhoBGKdynamics<T,DESCRIPTOR>;

#define USE_SMAGORINSKY //default

2nd Change:
// Material=1 –>bulk dynamics
//sLattice.defineDynamics<BulkDynamics>(superGeometry, 1);
#ifdef USE_SMAGORINSKY
using BulkDynamics = SmagorinskyBGKdynamics<T,DESCRIPTOR>;
sLattice.defineDynamics<BulkDynamics>(superGeometry, 1);
//sLattice.setParameter<collision::LES::Smagorinsky>(T(0.15));
sLattice.setParameter<collision::LES::Smagorinsky>(0.15);
#endif

and so I am an error message:

So is there any solution for that? Or there is there any other way to change Cavity2D in Turbulent Form. If there please suggest.
