MagicDraw/Cameo support for the SysML Parametric Diagram and ConstraintBlocks for equations and mathematics is excellent, and it integrates with powerful maths engines such as Mathematica. It CAN be used on industrial strength real-world projects.
The SysML Parametric Diagram and the ContraintBlock technology for equations and mathematics is clever, powerful, useful, and integrates well with the other model-based engineering aspects of SysML.
MagicDraw/Cameo can parse the 'text' field of some mathematical Requirements and populate the constraint (and also then the constraint parameters) of a ConstraintBlock that refines a Requirement (your mileage varies).
The constraints and parameters in Figure D.33 are detailed in Figure D.34 in Block Definition Diagram format. Note the use of valueTypes [ValueTypes] originally defined in Figure D.2. Source OMG Systems Modeling Language (SysML) 1.6

Figure D.26 defines the various model elements that will be used to conduct analysis in this example. It depicts each of the constraint blocks/equations that will be used for the analysis, and key relationships between them. Source OMG Systems Modeling Language (SysML) 1.6
The context for the usages of constraint blocks shall also be specified in a parametric diagram to maintain the proper namespace for the nested properties. Source OMG Systems Modeling Language (SysML) 1.6
This allows a value property (such as an engine displacement) that may be deeply nested within a containing hierarchy (such as vehicle, power system, engine) to be referenced at the outer containing level (such as vehicle-level equations). Source OMG Systems Modeling Language (SysML) 1.6
