%TOUCH_solid%
boundary points activated by flow (non-geometrical criterion)
Same activation behavior as %TOUCH_liquid%. In the initial filling phase, interior points close to the boundary are projected onto the boundary elements.
The contrast to %TOUCH_liquid%, fixed tear-off criteria are applied. Free surface points are allowed to tear off from a boundary if
- tension forces are pulling the point, and
- the velocity in normal direction is non-zero, and
- the point was on the boundary for at least one time step.
