The consideration of electromechanical interactions plays an important role at the development of mechatronic systems. Discrete models of electrical and mechanical systems, given by networks and multibody systems, are often used to investigate the system dynamics. The coupling of two engineering tools with special features in the corresponding domains (Simplorer - electrical engineering and alaska - mechanical systems) promises an equivalent high performance in physical and mathematical modelling in both electrical and mechanical systems. The paper describes the problems to be solved in order to obtain correct results and a comfortable handling.
