Calibrated thermal and fluid simulation for the moments engineering teams need to commit — across aerospace, food processing, oil & gas, water technology, and data centres.
Each project becomes a pre-digital twin of the physical product — used during design to test geometry, materials, and operating conditions before manufacturing begins.

Pressure drop prediction, flow coefficient validation, cavitation onset, internal flow visualisation.
Surrogate models trained on CFD data — a pre-digital twin of the data hall for rapid thermal prediction across rack and cooling configurations.
A CFD (Computational Fluid Dynamics) consultant uses validated solvers to simulate how heat and fluids behave inside engineering systems — before the system is built. We're brought in to predict thermal performance, identify failure modes, optimise designs, and validate engineering decisions across aerospace, food processing, oil & gas, water technology, and data centres.
If your team needs CFD on one to ten projects a year — or you're hitting a deadline without the licences, hardware, or specialist time to mesh and solve — a CFD consultancy is faster and cheaper than building the capability in-house. Typical engagements run 2–8 weeks per project.
Conjugate heat transfer, multiphase flow (Euler-Euler TFM, CFD-DEM), porous media (Ergun, Darcy-Forchheimer), reacting flows, 1-D system simulation, and ROM / surrogate model development. We work in ANSYS Fluent, OpenFOAM, and 1-D platforms.
Numerix Design is based in Bengaluru, India. We deliver CFD and thermal consulting projects globally — defence and space programme work in India, food and water technology projects across Asia, and data centre thermal optimisation worldwide.
