GfsBcNeumann
From Gerris
GfsBcNeumann is used to impose a Neumann boundary condition i.e. the value of the derivative normal to the boundary of a given variable. The normal vector always points toward the outside of the simulation domain.
The syntax in parameter files is
GfsBcNeumann V [ GfsFunction ]
where V is the name of the variable and the GfsFunction is the value of the normal derivative.
Examples
- Turbulent air flow around RV Tangaroa
- Air-water flow around a Series 60 cargo ship
- Small amplitude solitary wave interacting with a parabolic hump
- Circular dam break on a sphere
- Circular dam break on a rotating sphere
