modelling and simulation

Engineering certainty through modelling and simulation

We create virtual prototypes that predict how your products and systems will behave in the real world, helping you optimise performance, reduce risk, and accelerate delivery.

Why modelling and simulation matters

When physical testing is expensive or impractical, simulation gives you the power to test, iterate, and refine designs safely and efficiently. Xi’s expertise spans structural, thermal, acoustic, fluid, and electromagnetic systems, so you can model the full picture, not just one part.

How we build reliable models

Our engineers use advanced simulation platforms (COMSOL, ANSYS,
and bespoke solvers) to replicate the complex physical interactions
within your system. We integrate your measurement data to validate
and refine models, ensuring the digital twin accurately reflects
real-world performance.

  • COMSOL multiphysics modelling
  • ANSYS structural and thermal analysis
  • custom solvers for niche physics problems
  • validating using real measurement data

Risk Reduction

Validate performance before manufacture or deployment.

Confidence

Use data-driven insight to support investor or regulator decisions.

Our expertise in action

See how Xi uses advanced modelling and simulation to de risk design, cut prototyping and improve performance.

Xi Engineering Consultants uses modelling and simulation to explore how products and structures behave before they are built, from Multiphysics analysis of complex components to full system models for turbines, buildings and transport. These case studies show how virtual testing helps clients uncover problems early, balance performance with cost and move into manufacture or construction with far greater confidence.

Transducer design optimisation

Xi Engineering Consultants modelled and optimised a piezoelectric transducer for structure borne data transmission, delivering a robust, low risk design that works where electromagnetic communication fails.

Removing structural vibrations using simulation

Xi Engineering Consultants uses targeted measurement and simulation to diagnose structural vibration problems and design practical mitigation, protecting comfort and sensitive equipment in demanding buildings.
