Cameo Simulation Toolkit allows you to use an external Evaluator to evaluate an opaque expression in your model. Therefore, you can use any language supported by the external Evaluator in the body of the opaque expression.



You must specify the name of the language in the opaque expression. If you do not specify the language of the opaque expression, Cameo Simulation Toolkit will use the Default Language option specified in the Simulation Framework group in the Project Options dialog as follows.

If the language of expressions of constraints of a SysML Constraint Block is not specified, Cameo Simulation Toolkit will use the Evaluator, specified in the Default Parametric Evaluator option in the Parametric Evaluator group in the Project Options dialog, to solve the expressions as follows.
