Intuitive engine design, durability and NVH


ENGDYN is a dedicated three-dimensional engine analysis tool essential to the design and development of the crank train, engine structure and associated components such as bearings, connecting rods and engine mounts. By offering a range of complexity for components, oil film models and solvers, ENGDYN can be used throughout the entire development programme, from concept through to production.

ENGDYN's application range expands 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.
