GfsBoundaryOutflow

From Gerris

GfsBoundaryOutflow allows "free" outflow (and inflow) on a given boundary.

The syntax in parameter files is

[ GfsBoundary ]

It is identical to (for a boundary normal to the y-direction)

Boundary {
  BcDirichlet P 0
  BcNeumann V 0
}

Examples

• B\'enard--von K\'arm\'an Vortex Street for flow around a cylinder at Re=160

GfsBox { right = BoundaryOutflow }

• Vortex street around a "heated" cylinder

GfsBox { right = BoundaryOutflow }

• Parallel simulation on four processors

GfsBox { right = BoundaryOutflow }

• Boussinesq flow generated by a heated cylinder

GfsBox { bottom = BoundaryOutflow }

GfsBox { top = BoundaryOutflow }

• Starting vortex of a NACA 2414 aerofoil

GfsBox { right = GfsBoundaryOutflow }

• Wingtip vortices behind a rectangular NACA 2414 wing

GfsBox { right = GfsBoundaryOutflow }

GfsBox { right = GfsBoundaryOutflow }

• Flow through a divergent channel

GfsBox { right = BoundaryOutflow }

• Potential flow around a thin plate

  right = BoundaryOutflow 

• Translation of an hexagon in a uniform flow

GfsBox { right = BoundaryOutflow }

• B\'enard--von K\'arm\'an vortex street behind a cylinder translating in a fluid at rest

    right = BoundaryOutflow
