Expressions are used in various places in Simulation Studio:
in writing expressions in the Expression field of a Formula block;
in writing Boolean criteria in the Attribute Rule field of the Unbatch, Entity Filter, Entity Group Holder, Resource Stats Collector, and Resource Scheduler blocks; and
in writing Boolean criteria in the Attributes field of the Seize and Release blocks.
All blocks that have an Attribute Rule or Attributes field also have a pop-up editing window for writing expressions. You open the editing window for expressions by right-clicking in the Attribute Rule or Attributes field and selecting the option Edit. This appendix documents the operators and functions for Simulation Studio expressions.
