v3.8.1

✨ Added

• Added Reactor component #481
• New feature to display simulation outputs on model diagrams #482

⬆️ Model updates
Nothing to do to update a model from v3.8.0 to v3.8.1, except if you want to use the feature showing the output in model diagram.

v3.8.0

✨ Added

• Added sensors name in sensors icons PR#473
• Added sensor background color feature in sensors icons PR#477
• Added a feature to show the causality in sensors icon PR#479
• Added units for volume, surface tension, dynamic viscosity and thermal conductivity PR#474
• Added input connectors for all units PR#475
• Added Fogging component PR#460

🐛 Fixed

• Fix flow direction in valve PR#468

⬆️ Model updates

Nothing to do to update a model from v3.7.0 to v3.8.0, except if you want to use the feature showing the causality in sensors icon.

v3.7.0

Will be breaking for faulty model containing a condenser, because it adds a fault variable

• ✨ Added PR#457

  • compressor and gas turbine internal faults
  • condenser Qv_cold_in decrease,
  • missing Fuel and FlueGases pipes
  • with all corresponding tests

• 💥 Pressure losses equations in Pipe, ControlValve and SlidingValve now use inlet density instead of mean density. This change can affect calibrated models. PR#450

v3.6.1

✨ Added

🆕 Added fuel valve component #446
✨ Add and correct initialization parameters in flue gases #436
✨ Add indicators in the HX models #443
✨ Added a warning if the steam admitted in the condenser is superheated #445
🆕 Tank component #434

🐛 Fixed

🔧 Initialisation parameters and unit tests of the multifluid heat exchangers fix for a better convergence #439
🔧 Added rho_0 as an initialization parameter in the FlowModel #440

💥 Changed

💅 Fixed all icons issues in #434

⬆️ Model updates

Nothing to do to update a model from v3.6.0 to v3.6.1, except potentially changing component positions for gas heat exchangers.

v3.6.0

This release marks the open source release of Metroscope Modeling Library under Modelica License 2.
The older versions remain accessible in this repository.

Other minor changes are included in v3.6.0, see Changelog for more details.

v3.5.0

v3.5.0 is mainly a refactoring release with variables and component renaming. The breaking changes are:

• Steam turbine now has no nozzle, there is a specific nozzle steam turbine
• Gas turbine does not have a compressor power connector (simply connect the compressor to the generator)
• Renaming of internal variables might break start value models
• Renaming of parameters (heat exchange surfaces, coefficients, valve Cv_max, pump minimum efficiency rh_min)

See Changelog for details.

v3.4.1

Non-breaking Changes

• Sensors now contain a flow model to ease convergence
• Pipes now can have a unique flow direction according to the pressure difference direction

v.3.4.0

Non breaking changes:

• Updated leak model so they use inheritance
• Changed default unused value for enthalpy in opposite flow direction to 1e6
• Fixed the outlet temperatures of the evaporator to be equal to what we read in the connectors

Common breaking changes:

• fouling fault in Pipe and closed fault in SlideVale are changed to percentages. The values given to those faults should be a percentage (%) and not a value between 0 and 1. Therefore, it is a breaking change for faulty models in previous versions
• Abstract sensors connectors are renamed C_in and C_out: breaking change for topological models

CCGT Specific breaking change:

• Addition of a pipe (friction coefficient) in the CombustionChamber component

NPP Specific

No breaking changes

v3.3.1

Common Changes

• Added an internal fault valve_closed to the SlideValve component

CCGT Specific Changes

• Added PressureCut and Leak components for the flue gases medium

v3.3.0

Common change:

Fix start values of outlet flows in heater with internal leaks

CCGT Specific breaking change:

Correction of the sign of the nominal temperature drop in the hrsg_monophasic_HX and in the FuelHeater. This is a breaking change for CCGT models calibrated on previous versions.

NPP Specific

No breaking changes. Models working with v3.2.0 should be fully compatible
