FSL Version 5.5

Fuel System Library 5.5 is part of Modelon's 2024.1 release.

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

New Features

  • A new Tank Pre-Processing App version 1.0 has been released with the library. The app can process complex and finer tank meshes and returns data which are used for simulation in Modelon Impact. Refer to the installation guide and tutorial on how to use the app.
  • Moment of inertia computation is added to the Modelica and implicit external geometry kernels.


  • Media functions that were redeclared in Template packages are now replaceable. Now functions can be redeclared after extending from existing Template packages rather than needing to create new Template packages.
