Our Expertise

Fluid Dynamics Simulation (CFD)

We model and solve complex, high-fidelity fluid flows (turbulent, rotating, multiphase, etc.) using open-source solvers.

Scientific Software Development

We develop production-grade numerical solvers and simulation tools in C++ and Python, tailored to your problem, with automated workflows and pipeline orchestration.

Fluid-Structure Interaction (FSI)

We simulate the multiphysics coupling between unsteady fluid forces and deformable or moving structures using custom-built solvers.

Numerical Modelling & Methods

We derive and implement physics-based numerical methods tailored to your problem, faithfully capturing real physical behaviour.

Shape Optimisation

We combine genetic algorithms and automated CFD evaluation pipelines to drive aerodynamic and geometric design toward optimal performance.

Finite Element Analysis (FEA)

We run high-fidelity finite element simulations for structural, thermal, and dynamic problems, from linear to highly nonlinear calculation steps.

HPC Pipeline & Cluster Workflows

We design and automate scalable, HPC-ready parallel simulation pipelines on PBS and Slurm clusters, from job submission to result extraction and post-processing.

Why NumFlow?

We turn complex physics into validated deployable simulation tools.

Reason 1

PhD-level research

We don't just run simulations; we build the methods behind them. Every solution starts from the governing physics and is verified and validated (V&V) against experimental benchmarks.

Reason 2

Full-stack open-source tools

From geometry and meshing to solver configuration and HPC deployment, we handle the entire end-to-end pipeline using open-source tooling.

Reason 3

AI-accelerated R&D delivery

We leverage AI coding agents and modern development workflows (automated code generation, pipeline orchestration, rapid prototyping) to accelerate delivery without compromising engineering standards.
