Cameo Simulation Toolkit: HOWTO test an EnumerationLiteral value in a (Groovy) script in an OpaqueAction/Behavior. Use kind.name == "value"

Webel: SysML4Mathematica: POLICY: Handle flow sign changes via a single negative (not duplicated and "adjusted" algebra). This strategy may come at a very slight performance cost (for benefit of more robustness).

MagicDraw/Cameo v19SP3: The display of units can't be disabled on the initialValues compartment for context-specific values, which can lead to inconsistencies when an OpaqueExpression that references value property names is used.

MagicDraw/Cameo v19SP3: UML/SysML: HOWTO Set an OpaqueExpression on a Slot that seems to be stuck on a numerical value.

MagicDraw/Cameo v19SP3: vs SysPhS-1.1: OpaqueExpression for Slot value exports to Modelica as 'null' if only uses a single variable. WORKAROUND/HACK prefix the variable with '1 *' [FIXED in v2021x]

UML Class Diagram

The vendor-specific Action Language Helper (ALH) API can be accessed from all of the various action scripting languages available in MagicDraw, Cameo Systems Modeler, and Cameo Simulation Toolkit

An OpaqueExpression specifies the computation of a set of values either in terms of a UML Behavior or based on a textual statement in a language other than UML.
