Dymola 2021 Available

Dassault Systemes have announced the availability of a new version of Dymola. The key highlights of the Dymola 2021 release are:

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

New user interface

  • The model tabs have been moved to the top of the model window.
  • Plotting capabilities have been generalised to allow a matrix of plots in each window, and to provide additional result documentation for each plot window.
  • A Moving Average operator allows smoothing of plotted signals. 

As you may know, a new User Interface was introduced in the previous release, Dymola 2020x. For those who haven’t already made the change, please watch the introductory video below:

  • Several key improvements in simulation performance and robustness of complex models.
  • Possible to create snapshots of the result while simulating and to control the output interval from the model. 
  • Parameter sweeping can now handle more than two parameters.
