I have also noticed that in AdvectionDiffusionTRTDynamics the collision function is:
cell[iPop] -= _omega2 * (fPlus[iPop] – fEqPlus[iPop]) + this->_omega * (fMinus[iPop] – fEqMinus[iPop]);
whereas in TRTDynamics:
cell[iPop] -= _omega * (fPlus[iPop] – fEqPlus[iPop]) + _omega2 * (fMinus[iPop] – fEqMinus[iPop]);
The omega related to the viscosity and the free parameter omega are switched in the collision.
