Case Studies
A case study analysing data center cooling airflow with Boreas, an FFD-based solver. The subject is a measured 151-rack, 344 kW facility whose layout and operating conditions are published, and the analysis produces the steady-state temperature field and per-rack inlet and outlet temperatures.

Research
The CPU path of a GPU-oriented solver was slow, so we added OpenMP and then went on to try a hybrid with MPI. The hybrid led by 11% on 8 cores but lost the lead at 32, and we found out why most CFD codes go pure MPI on the CPU.

Research
We built a controller that adjusts CFL in real time during a CFD run using a commercial LLM, and attached it to the Wake solver. The LLM alone diverged; combined with a fast rule-based safety layer, the hybrid converged 27% faster than a human-tuned constant CFL.

Research
We developed a GNN-based aerodynamic surrogate model that predicts aircraft six-component coefficients from a surface mesh and flight conditions, with training and desktop inference separated for secure engineering environments.

Case Studies
Internal flow in an aircraft S-duct intake analysed with both a conventional CFD code and a GPU-based solver, comparing computational efficiency and accuracy.

Validation
Aerodynamic noise in automotive HVAC systems matters more in the electric vehicle era. This case study predicts it directly with Flow360, a GPU-native CFD solver, and compares the sound pressure spectra against experiment.

Validation
A UV fluence rate simulator built on the MSSS model replaces the full radiative transfer equation with an absorption-dominant simplification. It predicts the radiation field in water treatment and semiconductor UV systems effectively, and agrees closely with measurement even in real reactor geometries.

Research
This study uses sensor data to monitor UV oxidation in semiconductor ultrapure-water production, combines a CFD and photochemical digital twin with edge AI to predict future TOC and equipment condition, and links those predictions to lamp power, switching control and fault-compensation operation.

Case Studies
A CFD case study of the ONERA M6 wing run on Flow360, comparing three meshes, two turbulence models and four GPUs against published data.

Case Studies
A Flow360 analysis of the N1G supersonic missile test model, a public wind-tunnel benchmark for missile aerodynamics.

Case Studies
A thermal-flow analysis of a super-premium efficiency induction motor at rated load. Anisotropic conduction in the windings and cores, Taylor vortices in the air gap and the external fan flow were modelled together, and the winding temperature came within 5.0°C of measurement.

We developed a procedure that blends a non-circular intake throat smoothly into the circular engine face, then quantified flow distortion against SAE-ARP-1420-B. Two geometries differed by only 0.05% in pressure recovery, yet their DC60 values were an order of magnitude apart.
