Dassault Systemes have announced the availability of a new version of Dymola. The key highlights of Dymola 2022x release are:

Dymola is a physical modelling and simulation tool, used for model based design of complex systems.

Additions and improvements in Dymola

  • Visualization of Modelica class hierarchies 
  • Steady state solver interface 
  • Improvements of plotting
  • Improved warning for unconnected physical connectors 
  • Improvement of the explicit Runge-Kutta solver 
  • Option to activate parallel Jacobian update 
  • Support of System Structure and Parameterization (SSP) import 
  • Improved selection of FMU type depending on if inline integration is selected 
  • Cloud service for license management (Managed DSLS) 
  • Extended checking for Termination of Support (TOS) in license 
  • Migration to new Linux platform
  • Postponed discontinuation of dymosim DLL support
  • eFMI: An open standard for physical models in embedded software (Limited Availability)


  • Improved user interface for static and dynamic steady-state simulation, including comparison of solutions and checks that steady-state was achieved.
  • Plot a 1D discretized component, for example the temperature profile of a pipe. 

Model editing

  • Import models described by System Structure and Parameterization (SSP files).
  • Visualize model structure with automatically generated UML diagrams.

Library and installation

  • Interface to Multiflash with Thermodynamics connector library
  • Option: license managed on a Dassault Systèmes server, no local license server setup.
