Engineering
Simulation & Analysis (FEA / CFD / Multiphysics)
Virtual testing that removes physical iterations and de-risks design decisions.
Overview
What this capability means at OneFit Projects
We run structural, thermal, fluid, dynamic and coupled simulations to predict how designs behave before metal is cut. Results are correlated with test data wherever possible and reported in a format that engineers, regulators and auditors can follow.
How we engage
- Scoped studies with fixed deliverables and price
- Turnkey packages delivered with our engineering, quality and digital teams
- Embedded specialists working in your tools and processes
- Retained support under a framework agreement
Service lines
8 ways we deliver simulation & analysis
Structural FEA
Linear and non-linear static, contact, buckling, fatigue, fracture and creep analysis.
Dynamics & vibration
Modal, harmonic, random vibration, seismic, rotor dynamics, shock and drop-test simulation.
Thermal analysis
Steady-state and transient heat transfer, thermal stress, electronics cooling, cryogenic and furnace applications.
Computational fluid dynamics
Internal and external flow, multiphase, combustion, HVAC, cleanroom airflow, mixing and pump/valve performance.
Pressure equipment analysis
ASME VIII Div 2 design-by-analysis, nozzle loads, fatigue assessment and fitness-for-service to API 579.
Crash, impact & explicit dynamics
Drop, crash, blast and high-speed impact events for transport, defence and consumer products.
Optimisation
Topology, parametric and multi-objective optimisation to cut mass, cost and material without sacrificing performance.
Multiphysics & system simulation
Fluid-structure interaction, electro-thermal, magnetics and 1D system models for hydraulics and thermal networks.
