Simulate with complex geometries and complex physics
%ACTIVE_interval%
active during simulation in time intervals
%ACTIVE_interval% determines if the boundary is active during the actual simulation. It does not imply that the boundary will be active in the initial filling phase.
One or multiple time intervals need to be given with this statement, e.g.
ACTIVE($noinit_temporalN$) = ( %ACTIVE_noinit%, %ACTIVE_interval%, t_on_1, t_off_1, ..., t_on_N, t_off_N ) # N time intervals.
