Xi has been using advanced computer simulation since its inception. Using COMSOL we have continued pushing the boundaries of what is possible through simulation. Xi works closely with COMSOL and is one of only five certified COMSOL consultants in the UK and one of less than eighty worldwide.

COMSOL Multiphysics® Certified Consultant

COMSOL Multiphysics® is a simulation platform that links different disciplines allowing Xi to simulate and predict the effects of many phenomena and processes. The electrostatic behaviour of headphone speaker drivers; the structural and acoustic response of wind turbines; the mechanical excitation of the drivetrain; Xi can explore any design challenge at any scale using simulation.

The capabilities of simulation are constantly evolving and Xi is at the forefront of these changes. We work closely with the COMSOL technical development team and often test new features and technics to push the software to its full potential. Xi simulations allow clients to test and explore new configurations and concepts efficiently and at a cost well below that of physical tests and experiments.

Our approach to modelling & simulation

Having real-world grounding is key to Xi’s success in simulation and modelling. Xi’s modelling team have hands-on engineering experience which is vital when accessing the validity of modelling outputs. Our philosophy is, where possible, to use actual physical measurements or other real-world data to improve accuracy and provide confidence in our models.

The Xi team comprises a strong group of multidisciplinary specialists, allowing us to work with a multitude of COMSOL modules. We are experts in applying design optimisation to a variety of sectors across all physical scales.

Our COMSOL expertise includes:

• Structural dynamics, vibration, fatigue and robustness
• Multibody dynamics used for example in drivetrains
• Acoustics
• Electromagnetics used in electrical motors and generators
• Electrostatics used in touch screens and speakers
• Piezoelectric and other MEMS devises
• Computational Fluid Dynamics

We work with clients all over the world including Europe, North America, Asia and Africa. Our work is regularly presented at international conferences and published in peer-reviewed articles. We have won multiple awards and our work on electrostatics and acoustics has been published in NASA Tech Briefs.
