Version 5.4

Fuel System Library 5.4 is part of Modelon’s 2023.2 release.

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

New Features

  • Added external code build files for Visual Studio 2022. Removed the build files of old Visual Studio versions 2008, 2010, 2012 & 2013. This change relates to the ExplicitExternalWithVisualization geometry kernel in complex tanks.


  • Modelica geometry kernel is restructured giving a 25-30% reduction in CPU time on the tested models (ComplexTankSTL and RockingTankHeatTransfer).
  • Updated the true length parameter default value in the lumped pipe to set as the direct length computed from the port positions. This could be changed by the user as needed.

Fixed Issues

  • Fixed an issue in the Volumes.ConvectiveSimpleTank model where spurious temperature and pressure were calculated when heat transfer was enabled for fixed acceleration on the "-z" direction.
