We accelerate your technology development, solving complex engineering problems by applying cutting-edge Multiphysics simulation and validating our models in real life, merging the real and virtual worlds to deliver economic benefit.
WORKING WITH Xi
The Xi team comes from an array of diverse disciplines, but we share one thing in common: a passion for solving complex engineering challenges.
Our advanced Multiphysics computer simulations are validated by physical measurements and data analysis. It’s this merging of the real and the virtual that makes Xi’s cutting-edge simulations among the most accurate in the world.
Xi works with companies of all sizes, across a broad range of industries and market sectors. Every project is different, and we tailor our approach to fit your needs: whether that means focusing on an individual aspect of your project, resolving unforeseen issues or providing holistic support across your entire development journey.
We typically engage with clients in one of three ways:
One-off projects
Access our expertise for diligence, independent assessment, as a resource buffer or just a sanity check.
R&D partner
Remove the need to develop in-house skillsets and avoid unnecessary long-term investment by having us join your R&D team to provide measurement, analysis and simulation.
Journey client
With capital investment, create a ‘Xi inside’ your organization by having us develop your in-house capability for validated advanced simulation or digital twinning.
