• The equality operator (= =) can be more precise when applied to continuous values, but the inequality operators ( > or < ) can be more robust and provide better performance.

• You can only set a termination condition for a Mechanism Dynamics analysis.

• The expression may not be longer than 1023 characters.

• The expression can include one or more variables.

• The equality operator (= =) can be more precise when applied to continuous values, but the inequality operators ( > or < ) can be more robust and provide better performance.

• While any expression may be used, it is a good idea to use an expression that extrapolates to a logical value (such as true/false).
