This package contains models and blocks from the Modelica Standard Library version 3.2.3 that are no longer available in version 4.0.0 The conversion script for version 4.0.0 changes references in existing user models automatically to the models and blocks of package ObsoleteModelica4. The user should manually replace all references to ObsoleteModelica4 in his/her models to the models that are recommended in the documentation of the respective model.

In most cases, this means that a model with the name "ObsoleteModelica4.XXX" should be renamed to "Modelica.XXX" (version 4.0.0) and then a manual adaptation is needed. For example, a reference to ObsoleteModelica4.Math.Matrices.LAPACK.dgeqpf should be replaced by Modelica.Math.Matrices.LAPACK.dgeqp3 (version 4.0.0). This usually requires some changes at the place where the class is used (besides the renaming of the underlying class).

The models in ObsoleteModelica4 are either not according to the Modelica Language version 3.4 and higher, or the model was changed to get a better design. In all cases, an automatic conversion to the new implementation was not feasible, since too complicated.

In order to easily detect obsolete models and blocks, all of them are specially marked in the icon layer with a red box.
