Thank you for choosing the ClaRa library for your simulation purposes!
The open-source Modelica library ClaRa provides its users with the capability to proficiently tackle tasks in the disciplines of thermal hydraulics and instrumentation and control pertaining to power plants and other kind of energy systems.

The ClaRa development team consists of the following partners:
- TLK-Thermo GmbH (Braunschweig, Germany)
- XRG Simulation GmbH (Hamburg, Germany).
Contents published in ClaRa have been contributed by different authors and institutions. Please see model documentation for detailed information on original authorship and copyrights.
Please read the following steps for a successful usage.
Installation:
- Copy the unzipped library files to your preferred folder
Currently, only DYMOLA provides full suppport of ClaRa. The development team has tested all models carefully using DYMOLA 2023x Refresh 1 which we therefore recommend to use it. However, we are committed to ensuring its compatibility with the OpenModelica (OM) environment (https://openmodelica.org/) and have made significant progress in this regard thanks to OM development team. More than half of the examples can now run in OM, and we will continue our efforts to expand this compatibility. For other tools' support please contact us via mail at info@powerplantsimulation.com.
- Get Access to the Library from DYMOLA
In Windows add an Environment Variable with the following properties: Variable name: ModelicaPath Variable value: path of the directory where ClaRa is located
How to do this on Windows 7: → click "Start" → rigth click on "Computer" → choose "Properties" option → in the "System" window click on "Advanced system settings" → in the "System Properties" window select the "Advanced" tab and click on "Environmental Variables" → now create a new variable "ModelicaPath" either in "System variables" (this makes your definition accessible for all users) or in "User variables for %your user name%" (this makes your definition only accessible for you and programs executed by yourself) → give the variable as value the path of the directory where ClaRa is located on your computer → click "OK" button → click "OK" button in "Environmental Variables" → click "OK" button in "System Properties Window" → close "System" window
Now open Dymola and ClaRa will be automatically opened. Additional libraries used by ClaRa will be automatically loaded once you open a ClaRa model using components from those libraries.
If you don not want install ClaRa on your computer then you can open the required libraries manually (in DYMOLA via the graphic menu: File → Open and File → Load, respectively). The libraries require are the following:
- TILMedia (for the calculation of media data)
- ClaRa ("Simulation fo Clausius Rankine Cycles")
- SMArtIInt ("for usage of (trained) TensorFlow models from within Modelica.")
- ClaRa_Obsolete (if you have already Power Plant models that you want to use with the new version of ClaRa then there might be some models that are deprecated)
You can also perform the steps named in alternative B automatically by running the ClaRa_StartUpDymola.mos located in ClaRa/Resources/Scripts.
