Demo ​​​​​​​CST Studio Suite ​​​​​​​Dymola ​​​​​​​

Dymola is a system level simulator from our sister brand Catia based on the Modelica language. You can use it very efficiently for Multiphysics system simulation.

With the release of CST Studio Suite 2021 we offer a new link to export S-Parameter data created by a full-wave solver or by CST Studio Suite schematic directly into a modelica class. The S-Parameter will be vector fitted to ensure passivity and causality and the written into an ABCD state space description. The so generated class can be simply drag n dropped into Dymola (or into the Behavioral Modelling app on the 3DExperience platform) and used in all system level simulations. I think this is a great bridge between both tools extending the usage of physics based macro models in system simulations. 

You can find this functionality in CST Studio Suite under Macros -> Results -> Import and Export -> Export S-Parameters to Modelica
