We use explicit algorithms for strong non-linear analyses. In particular for crash analyses, large deformations, thermal and fluid flow, including such effects like glass split and explosions.
Our engineering services apply to a number of different products, ranging from ship structures through railway and automotive structures to electronic devices. Most of our analyses use implicit calculations as a basic tool for static, fatigue, thermal, buckling and vibration analyses with linear and non-linear material behavior.
We apply CFD (Computational Fluid Dynamics) for solving a variety of fluid flow and thermal problems like optimizing air conditioning systems (HVAC) and to investigate the air velocity distribution around a running train. For fluid flow also SPH (smoothed-particle-hydrodynamics) algorithms are being applied. They enable quick lubrication simulations in gear boxes and simulation of water drop effects.
Our MBD/MBS (Multibody Dynamics or Multibody Systems) simulations are useful tools for calculating the dynamic loading for structures under investigation, belonging to different mechanical systems. As examples we present: the jacking system of a jack-up offshore unit, vehicle suspension systems and actuator forces in door-opening mechanisms.
Electro-magnetic (EM) calculations apply to all electric or electronic devices.Low Frequency investigations enable designing motors, actuators, transformers and sensors. High Frequency investigations, in turn, apply mostly to communication device analysis and optimization for radars and antennas. The electro-magnetic-compatibility (EMC) simulation of machine to machine or machine to man influence plays more and more vital part in a world full of electro and electronic devices.
