GfsAdaptVorticity

From Gerris

GfsAdaptVorticity uses a "cell cost" defined as the norm of the local vorticity vector multiplied by the cell size and divided by the maximum of the velocity norm over the whole domain.

The syntax in parameter files is:

[ GfsAdapt ]

Examples

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

  AdaptVorticity { istep = 1 } { maxlevel = 6 cmax = 1e-2 }

• Vortex street around a "heated" cylinder

  AdaptVorticity { istep = 1 } { maxlevel = 6 cmax = 1e-2 }

• Rayleigh-Taylor instability

  AdaptVorticity { istep = 1 } { maxlevel = 7 cmax = 2e-2 }

• Boussinesq flow generated by a heated cylinder

  AdaptVorticity { istep = 1 } { maxlevel = (y > 1.5 ? 0 : 8) cmax = 1e-2 }

• Turbulent air flow around RV Tangaroa

  AdaptVorticity { istep = 1 } { maxlevel = (x < 0.5 ? 8 : 0) cmax = 1e-2 }

• Coalescence of a pair of Gaussian vortices (Gerris logo)

    AdaptVorticity { istep = 1 } { cmax = 1e-2 maxlevel = 12 }

• Convergence for the three-way vortex merging problem

  AdaptVorticity { istep = 1 } { maxlevel = LEVEL cmax = 4e-3 }

• Momentum conservation for large density ratios

    AdaptVorticity { istep = 1 } { cmax = 0.3 maxlevel = level }

• Translation of an hexagon in a uniform flow

  AdaptVorticity { istep = 1 } { minlevel = 4 maxlevel = 7 cmax = 1e-2 }
