Detailed Description

template<typename T, template< typename U > class Descriptor>
class plb::RLBdynamics< T, Descriptor >

Generic implementation of the Regularized BGK dynamics.

This implementation is valid for isothermal models only. This model is substantially more stable than plain BGK, and has roughly the same efficiency. However, it cuts out the modes at higher Knudsen numbers and therefore cannot be used in the regime of rarefied gases.
