GfsSolidMoving

From Gerris

GfsSolidMoving is used to define moving solid boundaries. It is only valid within a GfsSimulationMoving simulation.

The syntax in parameter files is:

[ GfsSolid ] { level = [ GfsFunction ] }

where level defines the level of refinement to be used for the moving solid boundary.

The way the moving solid boundary actually moves is defined using GfsSurfaceBc.

Examples

• Translation of an hexagon in a uniform flow

  SolidMoving hexagon.gts { scale = 0.250001 } { level = 7 }

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

  SolidMoving { istep = 1 } cylinder.gts { tx = 0.4 scale = 0.025 } { level = 11 }
