Services

Simulation services,
from first question to verified answer.

Eight areas of expertise, one way of working: understand the physics, choose the right model, verify the numbers and explain what they mean for your design.

01 / External aerodynamics

Lift, drag and everything in the wake.

Forces and moments are only the headline. We resolve the pressure distribution, separation and wake structure behind them, so you know why a shape performs the way it does and what to change.

Questions we answer

  • What are the lift, drag and moment coefficients across the operating envelope?
  • Where does the flow separate, and how sensitive is it to incidence or yaw?
  • How do design variants compare under identical conditions?

Methods

  • Steady & unsteady RANS
  • DES & LES
  • Compressible flow
  • Boundary-layer meshing
  • Force & moment breakdown

02 / Internal flows

Pressure drop, distribution and what happens around the bend.

Pipes, ducts, manifolds and valves rarely behave like the textbook correlation. We show where pressure is lost, how flow splits between branches and where recirculation or dead zones form.

Questions we answer

  • What is the pressure drop, and where exactly is it lost?
  • Is flow evenly distributed between branches, passes or outlets?
  • Will a baffle, vane or geometry change fix it?

Methods

  • Steady RANS
  • Transient analysis
  • Porous-media models
  • Loss-coefficient extraction
  • Parametric geometry studies

03 / Heat transfer & thermal management

Every temperature field tells a story.

Heat moves through fluids and solids together. We couple them with conjugate heat transfer to find hot spots, size cooling and show how much margin a design has at its worst-case condition.

Questions we answer

  • Where are the hot spots, and what are the peak temperatures?
  • Is natural convection enough, or does the design need forced cooling?
  • What duty and pressure drop will the heat exchanger deliver?

Methods

  • Conjugate heat transfer
  • Natural & forced convection
  • Radiation
  • Transient thermal
  • Electronics cooling

04 / Turbulent & unsteady flows

The right turbulence model for the question.

A steady RANS run answers many questions quickly; others need the unsteady structures resolved. We choose between RANS, hybrid and scale-resolving approaches on what the decision demands, not on habit. How we choose

Questions we answer

  • Does the flow shed vortices, and at what frequency?
  • What are the mean and fluctuating loads?
  • Is RANS sufficient here, or is a scale-resolving run justified?

Methods

  • k-ε & k-ω SST
  • Spalart–Allmaras
  • DES & DDES
  • LES
  • Spectral analysis

Particle tracking · Illustrative

05 / Multiphase & moving systems

Multiple phases. Connected behaviour.

Interacting fluids, dispersed particles and moving components change the problem. We pick the multiphase and mesh-motion approach that fits your application and the level of detail you need.

Questions we answer

  • Where does the free surface go during filling, draining or sloshing?
  • Where do particles or droplets travel, separate and deposit?
  • How does a rotating component perform across its speed range?

Methods

  • Volume of fluid
  • Eulerian multiphase
  • Particle tracking
  • Rotating & moving meshes
  • Fluid–structure interaction

06 / HVAC & ventilation

Air where you need it.

Supply and extract positions, heat loads and buoyancy decide whether a room is comfortable, a cleanroom stays clean or an enclosure stays cool. We model the air path before anything is built.

Questions we answer

  • Does supply air reach the occupied or critical zone?
  • Are temperature and air speed within comfort or process limits?
  • How quickly are heat and contaminants removed?

Methods

  • Buoyancy-driven flow
  • Species transport
  • Age-of-air analysis
  • Diffuser modelling
  • Transient studies

07 / Computational quantum chemistry

Small interactions. Fundamental insights.

When the answer lies in how molecules behave, we use density functional theory and molecular modelling to compute structures, energies and pathways, with the method chosen around your research question. Choosing a functional

Questions we answer

  • What is the stable geometry of this molecule or complex?
  • How strongly do two species interact or bind?
  • What is the energy barrier of a reaction step?

Methods

  • Density functional theory
  • Geometry optimisation
  • Electronic structure
  • Potential-energy scans
  • Molecular interactions

08 / Simulation support

Stuck? Send us the case.

Not every project needs outsourcing end to end. If a case will not mesh, converge or agree with experiment, send it as a solving request: we diagnose the setup, fix what is wrong and explain what we changed. Send a solving request

Typical requests

  • A solver that diverges or stalls
  • A mesh that fails quality checks
  • Results that disagree with test data

What you get

  • Root-cause diagnosis
  • Corrected setup
  • Mesh recommendations
  • Best-practice notes
