Dr. Jeremy Gibbs has developed a tool which operates on the 1D Stochastic Burgers Equation, allowing insight into turbulence without having to generalize to the fully-3D case and thus remaining very computationally cheap. PyBurgers offers a direct numerical simularion mode and an LES mode with 4 subgridscale options. You can read more about it and find the the code on the PyBurgers repository
