What stage is your problem at?
All three pillars share the same foundation: the model is calibrated against measured data before it is used to draw conclusions. The difference lies in the need: a diagnosis, a new design, or a tool that supports continuous operation.
Performance engineering

The equipment runs but underperforms: high consumption, skewed distribution, emissions over the limit. We start with on-site measurement and diagnosis; simulation is used to trace the root cause.
Performance engineering →Simulation & virtual engineering

The equipment is not yet built, or the retrofit option is not yet verified. Test it virtually before investing in hardware, comparing KPIs across options on the same model.
Simulation & virtual engineering →Digital twin & Engineering AI

A simulation answers once; operation needs answers continuously. We turn the engineering model into a tool that runs every day on live operating data.
Digital twin & Engineering AI →Three pillars, one validation workflow
Whether you need one answer, a design or a tool that runs daily, the model goes through these four steps before it is used to draw conclusions.
Collect operating data
Drawings, operating conditions, on-site measurements — CFDWAYS provides the minimum checklist.
Build & calibrate the model
The model is used only after it matches existing measurements; the error is reported with the results.
Compare options
Retrofit or new-design options run on the same model with the same KPI set.
Measure after the change
KPIs measured after the retrofit are compared with the prediction; these are the figures on the project cards below.
Measured results
Three representative projects — the problem, the approach and the outcome measured afterwards.
