Incompressible Navier-Stokes Unit
IncompNS unit solves incompressible Navier-Stokes equations in
two or three spatial dimensions. The currently released implementation
allows for both constant and variable density throughout the simulation domain.

Multistep and Runge-Kutta explicit projection schemes are used for time
integration. These methods are described in Armfield & Street 2002, Yang
& Balaras 2006, and Vanella et al. 2010. Implementations using a
staggered grid arrangement are provided for both uniform grid (UG) and
PARAMESH adaptive mesh refinement
Grid implementations. The
BiPCGStab Poisson solvers con be employed for
AMR cases, whereas the homogeneous trigonometric solver + PFFT can be
used in UG. Typical velocity boundary conditions for this problem are
