E-Mobility Solutions

Romax Concept allows seamless collaboration across CAD, Multibody Dynamics (MBD) and CAE to reduce errors and time to market.

Designs can easily be taken from Romax Concept and converted into CAD models and drawings, optimised multibody dynamic models and used in any other Romax product for more detailed analysis.

No need to re-enter data at every stage of the design process, reducing potential for error and saving time.
