SysPhS vs Modelica: If you redeclare a PhSConstant (Modelica parameter) as a PhSVariable (Modelica variable) Modelica still treats it as a 'parameter'. You can end up with an unbalanced system with one equation too many!

SysPhS-1.1: Annex A.5: p.89: Figure 75: Humidifier blocks, ports, & component properties. Typo in name of value property 'litpSec2mLiptHr:Real' on WaterTank should be 'litpSec2mLitpHr:Real' (breaks export of redefining Property with correct name).

SysPhS-1.1: Annex A.5: Typo in Figure 98 redefining value property 'C2 : Time = 1.0{redefines C2,unit = second}', should be lower case 'c2' (compare with BDD Figure 79)

MagicDraw/Cameo: HOWTO: Create a redefining value property with a default value using drag-n-drop

MagicDraw/Cameo: On dragging a Property onto another Property set it as redefining, the multiplicity of the redefining Property is set to [0..*] if the redefined (dragged) Property only has <UNSPECIFED> Multiplicity

WISHLIST: MagicDraw/Cameo: Ability to set project-wide option to NOT set the multiplicity of a redefining Property to [0..*] on using drag-n-drop when the redefined (dragged) Property has <UNSPECIFED> Multiplicity

SysML: When using Property::defaultValue and Property::redefinedValue to carry a "shadow hierarchy" of redefinitions across an entire system hierarchy, considering using a user-defined keyword such as «configuration» or «scenario» on each redefining Block

SysPhS-1.1: GOTCHA: The term "initial values" is sometimes just used to refer to the start values for a simulation run in Modelica or Simulink. It does NOT always mean the additional context-specific values mechanism of SysML beyond Property::defaultValue

SysML: Using redefined Property and Property::defaultValue to create deep hierarchical value configurations of "initial values" configurations for SysPhS simulation is notoriously fiddly and requires experience and patience. Better tool support is needed!

SysPhS-1.1: Annex A.5: 'Figure 101: Heating Scenario Initial Values': HeatingCalculation1: no such value to redefine 'C1 : Time = 1.0{redefines C1,unit = second}', should be 'xIntg : Real' (compare with BDD Figure 77 and Parametric diagram Figure 88)

SysPhS-1.1: Annex A.5: redefinition 'humidifierSystem {redefines humidifierSystem}' incorrect in Figure 96: Humidifier System Scenario Initial Values

An alternative for specifying initial values of part properties in the ConnectedTanks is to specialize it and redefine the part properties with default values for various configurations ...

Unified Modeling Language 2.5.1

Prefer not rename Properties when redefining unless indicating a clear change in role.

If a Property has a specified default, and the Property redefines another Property with a specified default, then the redefining Property’s default is used in place of the more general default from the redefined Property.

Source

A derived Property may redefine one which is not derived. An implementation shall ensure that the constraints implied by the derivation are maintained if the Property is updated.

Source

Unified Modeling Language 2.5.1

Property is indirectly a kind of RedefinableElement, so Properties may be redefined. The name and visibility of a Property are not required to match those of any Property it redefines.

The specialization on the lower right restricts the number of cylinders to between six and eight, rules out any roll bar, and limits lug bolts per wheel to between 6 and 7, by giving the end path upper and lower values.

Source

The specialization on the lower left restricts the number of cylinders to four, requires a light roll bar, and a total of 24 lug bolts over all the wheels.

Source

The general block on the top does not restrict the bound properties, except the total number of lug bolts is required to be between 24 and 32, rather than 24 and 40 as the associations in Figure 8-15 allow.
