Webel vs SysPhS-1.1: Annex A.5: Humidifier: In the Webel version it will be tentatively assumed we are in fact dealing with a large humidified space like an office building NOT a single "humidified room" - despite the block name HumidifiedRoom in the spec

Webel vs SysPhS-1.1: Annex A.5: Humidifier: If the WaterTank::tankVolume 50,000 is measured in litres (L) the VaporPressureCalculation::volume within the HumidifiedRoom can't possibly be 25000.0 litre (L), it has to be 25000.0 (m^3), which is NOT a "room"

Webel vs SysPhS-1.1: Annex A.5: Humidifier: It is assumed that 'HumidityBalance::volume = 25,000' and 'VaporPressureCalculation::volume = 25,000' are the same fixed SpaceVolume in cubic metres (m^3).

Figure 62 and Figure 63 show the parametric diagrams of the tank and the pipe, respectively. Source SysPhS-1.1

Binding connectors link constraint parameters to simulation variables and constants, indicating their values must be the same. Source SysPhS-1.1

Component parametric diagrams show properties typed by constraint blocks (constraint properties), as well as component and port simulation variables and constants. Source SysPhS-1.1

Equations in constraint blocks are applied to components using binding connectors in component parametric diagrams. Source SysPhS-1.1

Also, the fluid flow in the tank, fluidFlow, is related to the change in the fluid height level fluidHeight over time and the cross-sectional surface area of the tank, surfaceArea. Source SysPhS-1.1

The tank constraints specify that the pressure in the tank, pressure depends on the height of the fluid level in the tank, fluidHeight, as well as properties of the fluid, fluidDensity. Source SysPhS-1.1

The sum of the fluid flow rates going through the two pipe openings is zero (the fluid is assumed to be incompressible). Source SysPhS-1.1

The magnitude of fluid flow rate through the pipe fluidFlow is the same as the magnitude of flow rates opening1FluidFlow and opening2FluidFlow going through the pipe’s openings, though the values differ in sign. Source SysPhS-1.1

The fluid flow rate through the pipe, fluidFlow, is proportional to the pressure difference by the constant resistance, which depends on the geometric properties of the pipe as well as fluidic properties. Source SysPhS-1.1

The pipe constraints specify that the pressure pressureDiff across it is equal to the difference of fluid pressures opening1Pressure and opening2Pressure at each end of the pipe. Source SysPhS-1.1

In this example, constraint blocks PipeConstraint and TankConstraint define parameters and equations for pipes and tanks, respectively, as shown in Figure 61. Source SysPhS-1.1

Component parametric diagrams show properties typed by constraint blocks (constraint properties), as well as component and port simulation variables and constants. Source SysPhS-1.1

Equations in constraint blocks are applied to components using binding connectors in component parametric diagrams. Source SysPhS-1.1

The source constraint specifies a sine wave signal with the parameter amp as its amplitude. The sink constraint displays (scopes) the output signal from the signal processor. Source SysPhS-1.1

The mixer constraint specifies the relationship between its one output and the two inputs that come from the low-pass and high-pass filters. The constraint defines the output to be the average of the inputs. Source SysPhS-1.1

The amplifier changes the signal strength by a factor gain, the low-pass filter eliminates the high-frequency components of the incoming signal, and the high-pass filter eliminates the low-frequency components of the signal. Source SysPhS-1.1

The amplifier, low-pass fil[t]er, and high-pass filter constraints show the input-output relationship of these components as the signal passes through them. Source SysPhS-1.1

In this example, a constraint block BinarySignalComponentConstraint defines the parameters for one input (ip) and one output (op), common to amplifiers, low-pass filters, and high-pass filters, as shown in Figure 51. Source SysPhS-1.1

The source constraint defines the voltage across it as a sine wave with the parameter amp as its amplitude. Source SysPhS-1.1

The source constraint defines the circuit’s electrical source. The ground constraint specifies that the voltage at the ground pin is zero. Source SysPhS-1.1

The constraints for the resistor, capacitor, and inductor specify the voltage/current relationship with resistance, capacitance, and inductance, respectively. Source SysPhS-1.1

The sum of the current going through the two pins adds up to zero (one is the negative of the other), because the components do not create, destroy, or store charge. Source SysPhS-1.1

The current i through the component is equal to the current going through the positive pin. Source SysPhS-1.1

These specify that the voltage v across the component is equal to the difference between the voltage at the positive and negative pins. The current i through the component is equal to the current going through the positive pin. Source SysPhS-1.1

In this example, a constraint block BinaryElectricalComponentConstraint defines parameters and constraints common to resistors, inductors, capacitors, and sources, as shown in Figure 40. Source SysPhS-1.1

All properties of a constraint block are constraint parameters, with the exception of constraint properties that hold internally nested usages of constraint blocks. Source OMG Systems Modeling Language (SysML) 1.6

Binding connectors, as defined in Clause 8 are used to bind each parameter of the constraint block to a property in the surrounding context. Source OMG Systems Modeling Language (SysML) 1.6

A constraint block typically defines one or more constraint parameters, which are bound to properties of other blocks in a surrounding context where the constraint is used. Source OMG Systems Modeling Language (SysML) 1.6

A constraint block is a block that packages the statement of a constraint so it may be applied in a reusable way to constrain properties of other blocks. Source OMG Systems Modeling Language (SysML) 1.6
