+### 1D3V Discontinuous Galerkin Fast Spectral (DGFS)
 This is a research code, written, so as to demonstrate that one can solve the full Boltzmann in ~6 seconds for common standard rarefied 1D problems such as couette/fourier/osc-couette.
 
 The codebase consists of the single/multi species high order discontinuous Galerkin solver utilizing Fast fourier transform for evaluating the collision operator.
