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).
Cameo Simulation Toolkit: You can use Mathematica as an external maths engine to share maths between an OpaqueBehavior and a ConstraintBlock using custom auto-loaded Mathematica functions (keeps a project nice and DRY and respects Single Source of Truth)
HOWTO: MagicDraw/Cameo: v2022Refresh1: JDK 11 download compatible with the modelling tools AND Apple Silicon (ARM) machines (such as M1 Max)
SysMLv1.x: Limitation: The 'body' (maths formula) of an OpaqueBehavior can't be synchronised (shared) with the 'constraint' of a ConstraintBlock (directly in the SysML model). Can lead to a WET (not DRY) model and breaks Single Source of Truth!
Webel: SysML4Mathematica: TIP: Representing Mathematica functions as SysML ConstraintBlocks modelled in SysML Parametric Diagrams and as Activities in SysML Activity Diagrams is super for analysing the dependencies between functions and their arguments!
SysML: Cameo Systems Modeler: A ValueType that does not extend Real might not always simulate correctly when used to type a constraint parameter of a ConstraintBlock (in a SysML Parametric Diagram) or to type a parameter (in a SysML Activity Diagram)!
Webel: SysML4Mathematica: SysML Parametric Diagrams are not well suited to modelling calculations with Blocks for MTools classes, or for modelling complex logic flow of Mathematica functions. Prefer SysML Activity Diagrams for those modelling cases.
TIP: Webel: SysML/UML: On the boundary of symbols for ConstraintParameters on a ConstraintProperty (ConstraintBlock usage) symbol in Parametric Diagrams use any placement or "ordering" of ConstraintParameter symbols that works for the diagram!
