NumFlow offers a focused set of high-end R&D services, from bespoke CFD campaigns to custom numerical software. Each engagement is led personally, with full scientific accountability.
01
CFD, FEA & FSI Simulation Services
We run high-fidelity CFD, FEA, and fluid-structure interaction simulations tailored to your geometry, physics, and operating conditions. From geometry preparation and meshing to solver configuration, execution on HPC clusters, and post-processing, we handle the full end-to-end simulation pipeline, delivering verified and validated (V&V), documented results.
Steady-state & transient CFD
FSI with moving/deformable structures
FEA: static, dynamic, thermal, and thermo-mechanical
Nonlinear analysis
Fracture & damage modelling
Complex geometry meshing
V&V & post-processing
02
Scientific Software Development
We build production-grade numerical tools and solvers tailored to problems that off-the-shelf software cannot address. From custom open-source OpenFOAM boundary conditions and solvers to fully automated simulation pipelines, every tool is delivered with documentation and deployment scripts.
Custom OpenFOAM solvers & libraries

Adjoint-based optimisation
Geometry parameterisation
CFD-coupled aero design
04
HPC & Workflow Engineering
We design robust, scalable, HPC-ready simulation workflows for PBS and Slurm clusters, from job submission and dependency chains to automated restarts, failure handling, and result extraction.
