MV-8002: Multi-Maneuver Events
In this tutorial, you will learn how to define end conditions for a maneuver or a sub-event, write parametric expressions, and to define events as multiple sub-events executed sequentially
- End conditions
- Conditions to end a particular maneuver before given simulation end time.
- Multi-maneuver events
- Events consisting for more than one maneuver – these maneuvers are executed sequentially.
- Parametric Expressions
- In a multi-maneuver event, expressions need to be re-evaluated before
the start of the maneuver in order to maintain the continuity of the signals.
- { Expression in Curly Braces }
- Instruction to driver to evaluate the expression before giving it to MotionSolve
- {SIGNAL}
- Evaluated as VARVAL(signal solver variable id)
- {SIGNAL_0}
- Evaluated as Signal Value at the end of last maneuver
- {%SIGNAL}
- Evaluated as {SIGNAL} – {SIGNAL_0}
