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.

• Integration with MATLAB (R2012a or later)
• Integration with MapleTM (17 or later)
• Integration with Mathematica (9 or later)
• Integration with OpenModelica (1.9.6 to 1.12.0)

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 in the Simulation Framework in group in the Environment Project Options dialog 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 in the Default Parametric Evaluator in the Environment Options dialog option in the Parametric Evaluator group in the Project Options dialog, to solve the expressions as follows.
