The basic approach of using the new defineDynamics call and setting the parameter seperately is correct.

In which order do you execute the calls? You need to first set the dynamics and then set the parameters (not just collision::LES::Smagorinsky but also OMEGA and so on).

If this doesn’t help I’ll have to see more of the code.
