%TOUCH_liquid%

boundary points activated by flow (non-geometrical criterion plus special tear-off)

Boundary points on these boundary elements are activated by free surface and interior points, controlled by ORGANIZE_ForceTouchCheckAtWalls. In the initial filling phase, interior points very close to the boundary will be projected to the boundary. To avoid this, use %TOUCH_geometrical% instead. In contrast to %TOUCH_solid%, no fixed tear-off criteria are applied. Instead, tear-off criteria can be defined by BC_TearOffCriterion.
