LCL Version 4.0

Liquid Cooling Library 4.0 is part of Modelon's 2026.1 release.

New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers.

Version 4.0 is updated to be compliant with Modelon Base Library 7.0.

New features

  • All LCL components now include a new parameter display_name in the Visualization tab. This parameter allows the component name to be displayed in the diagram layer for easier identification. The appearance and disappearance of component names can be controlled globally through Settings_LCL declarations.
  • Added new colormaps for visualization and updated the temperature and pressure contour visualization colormap from Jet to CoolWarm and TrafficlightColor. This change provides clearer and it gives effective representation of temperature variations.
  • Introduced the new package Interfaces and modified all two-port components to use these interfaces. This change makes it easier to work with replaceable components and redeclaration.

Improvements

  • Simulation runtime is speeded up when visualization is disabled. This is realized by removing unused code for visuals when is isn't active. Visualization is conveniently enabled or disabled for all compoents in a system-level by using this ExperimentBase base class (LiquidCooling.Experiments.Templates.ExperimentBase). Settings can also be given individually per compoent on the "Visualization" tab. The visualization_option setting was removed, as it was a duplicate to componentVisualizationSettings.visualization_option. Uses of the former will be converted with the supplied conversion script. Note a new limitation for the case that visualization is disabled at system level and enabled at component level: In this case the number of colors "n_colors" must be set at the compoentns where visualization is enabled.  
  • Improved the inner warning message for SystemInitOptions record to help identify the correct model.

Bug fixes

  • Corrected the spelling of record names of LiquidFlowResistance and GasFlowResistance. These fixes will not affect in the model results
  • Corrected the aggregate mass of the ExpansionVolume. The previous implementation over estimated the fluid mass (in most cases) because it was computed as the product of the liquid density and the total volume. The new implementation introduces a new option to include both or either of the fluid masses. The default is both. This fix will affect in the model results.

Conversion of User Libraries

User libraries will automatically be converted to version 4.0. These conversions are made using the included conversion script: LiquidCooling/Resources/Scripts/Convert_to_4.0.mos.
