Overview
Flow360 is a GPU-native CFD solver. It delivers the same numerical fidelity as a conventional solver while cutting solve time and compute cost substantially.
From the complex flow around a UAM with both wings and rotors through to automotive aeroacoustics, it is built for aerodynamic analysis.
Flexcompute builds the product; CLEW handles adoption, application and technical support in Korea. That relationship can be checked on the Flexcompute partner ecosystem page ↗. For current specifications, pricing and licence terms, the official Flexcompute page ↗ is the accurate source.
Speed and scaling
A CPU cluster loses efficiency as nodes are added. Flow360 uses GPU-specific methods to get scaling without that loss, alongside fast computation.
The practical result is that solve time stops being the bottleneck in a design review. Sweeping shapes through repeated steady-state runs, global optimisation, aeroacoustics — work that used to be dropped for schedule reasons — becomes plannable.
Actual run times depend on geometry, mesh size and GPU configuration. Checking with a representative case together gives a more accurate picture.
Physical models
GPU acceleration remains hard in CFD. Flow360 supports a broad set of physical models stably on top of it.

What CLEW does
Handing over a solver is not the job. The effect of high-performance CFD only lasts when the modelling, validation, automation and the way the team works are set up alongside it.
- 01 Evaluation
We review the problem scale, the physics and your current compute environment to scope what applies.
- 02 Pilot analysis
A representative case is actually run to confirm accuracy and the working flow.
- 03 Deployment and automation
Users, data and automation are set up so it fits the way you work.
- 04 Technical support
Modelling, convergence and performance problems get solved with you as adoption proceeds.
