 | **VeSyMA - Powertrain** | The Powertrain Dynamics library is a Modelica library for modelling rotating MultiBody systems like automotive powertrains. It has been designed to provide a convenient modelling methodology and deliver efficient simulation of these complex systems. | [Claytex](https://www.claytex.com/products/dymola/model-libraries/vesyma/powertrain/) | [Claytex](https://www.claytex.com/products/dymola/model-libraries/vesyma/powertrain/) & [Dassault Systèmes](https://www.3ds.com/products-services/catia/products/dymola/industry-solutions/) |
 | **VeSyMA - Suspensions** | Focused on the optimisation and analysis of automotive and on-road vehicles, where the basic vehicle layout is that of a pair of independent linkages connected by an anti-roll bar, the Suspensions library provides the user with a turn-key solution to detailed vehicle dynamic analysis. | [Claytex](https://www.claytex.com/products/dymola/model-libraries/vesyma/vesyma-suspensions/) | [Claytex](https://www.claytex.com/products/dymola/model-libraries/vesyma/vesyma-suspensions/) & [Dassault Systèmes](https://www.3ds.com/products-services/catia/products/dymola/industry-solutions/) |
 | **VeSyMA - Terrain Server** | The VeSyMA – Terrain Server Library provides an interface to the rFpro TerrainServer enabling high fidelity track data to be used in simulations running in Dymola. | [Claytex](https://www.claytex.com/products/dymola/model-libraries/vesyma/vesyma-terrain-server/) | [Claytex](https://www.claytex.com/products/dymola/model-libraries/vesyma/vesyma-terrain-server/) |
