Range of Solutions

ENGDYN has been designed to be used throughout the engine design programme from the early concept studies right through to detailed investigations of fully dynamic systems. ENGDYN achieves this by providing a range of modelling levels and solution methods in each area, from the simple to the complex.

ENGDYNs application range is also expanded by linking with other packages such as VALDYN and MATLAB/Simulink to perform fully coupled co-simulations with data passed between the codes at each time step. The links with VALDYN are fully integrated and allow systems such as the FEAD/READ or camshaft assemblies to be fully integrated with the powertrain analysis.
