ACTIVE

(required) define the activation behavior of the boundary elements of this part

The ACTIVE flag in the alias definition of a boundary element references an ACTIVE statement. The ACTIVE statement defines whether a boundary is active during the initial filling and/or the remaining simulation. Additionally, it specifies if the boundary fills points to the inside in the initialization phase of the simulation. Example:
ACTIVE($init_always$) = ( %ACTIVE_init%, %ACTIVE_always% ) # Definition of the Active statement ... begin_alias{} "car" = " BC$...$ ACTIVE$init_always$ IDENT%...% MAT$...$ TOUCH%...% MOVE$...$ CHAMBER1 " # Referencing the Active statement end_alias
