The development of this library has been a collaborative effort and many have contributed:

  • The essential parts of the media models have been implemented in the ThermoFluid library by Hubertus Tummescheit with help from Jonas Eborn and Falko Jens Wagner. These media models have been converted to the Modelica.Media interface definition and have been improved by Hubertus Tummescheit.
  • The effort for the development of the Modelica.Media library has been organized by Martin Otter who also contributed to the design, implemented part of the generic models, contributed to the User's Guide and provided the generic test suite Modelica.Media.Examples.Tests.
  • The basic idea for the medium model interface based on packages is from Michael Tiller who also contributed to the design.
  • The first design of the medium model interface is from Hilding Elmqvist. The design and the implementation has been further improved at the Modelica design meetings in

  • Hans Olsson, Sven Erik Mattsson and Hilding Elmqvist developed symbolic transformation algorithms and implemented them in Dymola to improve the efficiency considerably (e.g., to avoid non-linear systems of equations).
  • Katrin Pröß implemented the moist air model
  • Rüdiger Franke performed the first realistic tests of the Modelica.Media and Modelica_Fluid libraries and gave valuable feedback.
  • Francesco Casella has been the most relentless bug-hunter and tester of the water and ideal gas properties. He also contributed to the User's Guide.
  • John Batteh, Daniel Bouskela, Jonas Eborn, Andreas Idebrant, Charles Newman, Gerhart Schmitz, and the users of the ThermoFluid library provided many useful comments and feedback.
