Incompressible flows
The incompressible Navier-Stokes equations are solved using continuous finite element approximation.
ILES of Turbulent Flow around a Volvo Car
Implicit Large Eddy Simulation. The incompressible Navier-Stokes equations is computed by a residual based streamline diffusion stabilization, G2. Streamlines and magnitude of velocity for FEM solution with P1 elements for flow around a Volvo car with turbulent wake. The implicit Cranck-Nicolson method is used for the time discretisation. ~100K unstructured mesh points

Variable density incompressible flow
One can extend the incompressible solver that we develop to solve with additional advection equation either for density or temperature.
