This is a collection of setups for the compressible Navier-Stokes equations, which allow for the simulation of viscous compressible flows.
See the atl_eqn_nvrstk_module for details.
We distinguish setups for 2D (equation.name = 'navier_stokes_2d)
and 3D (equation.name = 'navier_stokes).
See these subdirectories for complete examples for the respective
equation systems.
Due to the compressibility, strong gradients may form in the fluid, leading to oscillations in high-order discretizations. To stabilize simulations it may, therefore, be necessary to employ some filtering techniques, see atl_stabilization_module. The shear tube example provides a configuration with a positivity preserving filter.
