Library Release

The new library is available from the Modelica Standard Library Homepage.

Release Notes

In this version, no new libraries have been added. The following major improvements have been made:

• The Documentation of the Modelica standard library was considerably improved: In Dymola 6, the new feature was introduced to automatically add tables for class content and component interface definitions (parameters and connectors) to the info layer. For this reason, the corresponding (partial) tables previously present in the Modelica Standard Library have been removed. The new feature of Dymola 6 has the significant advantage that all tables are now guaranteed to be up-to-date.
• Additionally, the documentation has been improved by adding appropriate description texts to parameters, connector instances, function input and output arguments etc., in order that the automatically generated tables do not have empty entries. Also new users guides for sublibraries Rotational and SIunits have been added and the users guide on top level (Modelica.UsersGuide) has been improved.
• Initialization options have been added to the Modelica.Blocks.Continuous blocks (NoInit, SteadyState, InitialState, InitialOutput). If InitialOutput is selected, the block output is provided as initial condition. The states of the block are then initialized as close as possible to steady state. Furthermore, the Continuous.LimPID block has been significantly improved and much better documented.
• The Modelica.Media library has been significantly improved: New functions setState_pTX, setState_phX, setState_psX, setState_dTX have been added to PartialMedium to compute the independent medium variables (= state of medium) from p,T,X, or from p,h,X or from p,s,X or from d,T,X. Then functions are provided for all interesting medium variables to compute them from its medium state. All these functions are implemented in a robust way for all media (with a few exceptions, if the generic function does not make sense for a particular medium).
• Many new models and functions have been introduced or improved in existing sublibraries.
