What is Computational Fluid Dynamics (CFD)?
Computational fluid dynamics (CFD) uses numerical models to predict how liquids, gases, heat, particles and chemical species move through or around a product, process or environment. A real system is converted into a digital domain, divided into a computational mesh and solved against the governing conservation equations. The result is a detailed view of quantities that are difficult, costly or unsafe to measure directly, including velocity, pressure, temperature, concentration, residence time and heat transfer. Used well, CFD does more than create visualisations: it explains why a system behaves as it does, tests credible alternatives and gives engineers evidence for design, safety, compliance and investment decisions.
Mansim is one of the most advanced companies in the world in developing CFD techniques and applying them to complex industrial problems. Originating from the ManchesterCFD team at University of Manchester, the CFD team at Mansim has an international reputation in accuracy, reliability and speed of computational simulations, evident from our awards, peer-reviewed publications and credentials of our team members.


When is CFD Used?

Airflow and Ventilation Analysis
Assess air distribution, ventilation effectiveness, pressure control, contaminant movement and thermal comfort in buildings, hospitals, cleanrooms, industrial facilities and data centres.

Safety, Compliance and Operational Resilience
Test smoke movement, gas dispersion, contaminant exposure, equipment failures and worst-case operating scenarios to support design approval and risk reduction.

Our Approach
01
Define the Challenge
We clarify the engineering question, performance criteria and required scenarios.
02
Review Inputs
We assess CAD, drawings, operating data and available measurements.
03
Build the Model
We prepare the geometry, mesh, boundary conditions and selected physical models.
04
Verify and Validate
We check convergence, mesh sensitivity and agreement with available evidence.
05
Test and Optimise
We compare operating conditions, design options, failure cases and mitigation measures.
06
Report Recommendations
We deliver clear findings, visualisations and practical engineering actions.
