GfsAdaptThickness

From Gerris

GfsAdaptThickness is used to control the level of refinement of interfaces defined using a GfsVariableTracerVOFHeight. With VOF methods reconnections of topologically separate interfacial regions generally occur whenever interface fragments are separated by less than two cells. GfsAdaptThickness allows to control the spatial scale at which this reconnection occurs. The mesh is adapted so that interface reconnections do not occur before the maxlevel parameter of GfsAdaptThickness is reached.

The syntax in parameter files is:

[ GfsAdapt ] NAME

where NAME is the name of the GfsVariableTracerVOFHeight describing the interface.

Examples

• Time-reversed advection with curvature-based refinement

    AdaptThickness { istep = 1 } { maxlevel = 8 } T
