04 / HPC & compute
Compute that scales
with the problem.
Large meshes, long transients and design sweeps need more than a workstation. Through our tie-ups with the major cloud platforms and our connections to India’s national compute programmes, every project runs on hardware sized for the physics, and you never have to provision or manage a cluster.
Cloud HPC tie-ups
- Oracle Cloud Infrastructure
- IBM Cloud
- Amazon Web Services
- Google Cloud
- Microsoft Azure
National compute programmes
- IndiaAI compute programmeGPU capacity made available under the IndiaAI Mission
- National Supercomputing MissionPARAM-series supercomputers hosted at national institutions
- Right-sized clustersCore counts matched to the mesh, so compute buys speed-up rather than idle cores.
- Parallel design sweepsVariants run side by side instead of one after another.
- Your choice of regionIndia-based cloud regions when data residency matters.

Rigour you can see.

We aim to be the simulation partner India’s engineers and researchers recommend, and we earn that one verified result at a time.
Physics first
We start from the governing physics and the decision you need to make, then choose the simplest model that answers it reliably.
Verified, not just converged
Mesh-sensitivity checks, residual and monitor histories, and comparison with data or correlations where they exist, all documented in the report.
Continuum to molecular

Compute on tap
Cloud tie-ups and connections to national compute mean mesh size and run count are set by the problem, not by the hardware to hand.

Clear visualisations, engineering interpretation and practical recommendations, rather than a folder of contour plots.
Support at every stage

09 / FAQ
Questions,
answered.
What services does CFD Pro offer?
We provide computational fluid dynamics (CFD), heat-transfer, multiphase and computational quantum chemistry (CQC) simulation: external aerodynamics, internal flows, thermal management, turbulent and unsteady flows, HVAC and ventilation, and DFT-based molecular modelling. We also take solving requests for existing cases that will not mesh, converge or validate.
See the full list on our services page.
How do I get started?
Fill in the project brief. Choose whether it is a project order, a solving request or a consultation, describe the problem and add whatever technical detail you have. We reply with a proposed approach, scope and quote.
What information do you need from me?
The more we know, the sharper our first reply. The most useful inputs are:
- Geometry: CAD, drawings or even a dimensioned sketch
- Operating conditions: flow rates, pressures, temperatures, heat loads, speeds
- Fluids and materials
- The question the simulation should answer, and the decision it supports
- Any test data or references to validate against
If you do not have everything, send what you have and we will work out the rest together.
How much does a study cost?
It depends on the physics, the complexity of the geometry, the mesh size, the number of cases and the deliverables you need. A single steady-state case costs far less than a transient or parametric campaign.
Send a project brief with as much detail as you can and we will reply with a quote for a defined scope. If you have a budget in mind, tell us and we will shape the study around it.
How long does a project take?
It depends on the physics and the number of cases. A single steady-state study is much quicker than a transient, multiphase or parametric campaign. We confirm the timeline in the proposal, so tell us your deadline in the brief.
What computing resources do you use?
We run on high-performance computing sized for each project. We have HPC tie-ups with Oracle Cloud Infrastructure, IBM Cloud, Amazon Web Services, Google Cloud and Microsoft Azure, and we can connect projects to India’s national compute programmes: the IndiaAI compute programme and the National Supercomputing Mission.
