FLOW-3D

What FLOW-3D does

Flow Science Software Private Limited operates from Pune as the wholly-owned Indian subsidiary of Flow Science, Inc., a US-based CFD software firm with more than 40 years of operating history. The India entity functions as the official distributor and regional support arm for the FLOW-3D software family across India, Bangladesh, Bhutan, Nepal, and Sri Lanka, employing a team of CFD engineers and QA staff operating within a small (11-50 employee) organizational footprint. As a distributor entity, its primary operational role is regional sales enablement, technical pre-sales, customer support, and localization for a software platform whose core IP, development roadmap, and most material commercial revenue likely concentrate at the US parent.

The underlying FLOW-3D platform is a computational fluid dynamics (CFD) suite specializing in free-surface flow simulation, anchored by the proprietary TruVOF (True Volume of Fluid) method, a registered trademark refined over decades. The product portfolio comprises a general-purpose core solver plus verticalized modules — FLOW-3D CAST (metal casting with 11 process workspaces), FLOW-3D AM (laser powder bed fusion, binder jetting, directed energy deposition), FLOW-3D HYDRO (hydraulic structures, dams, wastewater, stormwater), FLOW-3D WELD (laser welding physics), and FLOW-3D DEM (discrete element method). TruVOF enables accurate modeling of free-surface flows, multi-fluid interaction, phase change, moving objects, surface tension, and heat transfer. Pricing is not publicly disclosed; commercial licenses are sold via annual subscriptions to enterprises across metal casting, civil & environmental engineering, additive manufacturing, aerospace, automotive, energy, maritime, microfluidics, biotech, laser welding, coating, and consumer products. Academic institutions in the territory receive free 4-month research licenses and free teaching licenses as a top-of-funnel pathway, with paid extensions available for longer-term use.

The go-to-market combines direct enterprise field sales through technical sales engineers with channel distribution through the India subsidiary, supported by content marketing (case studies, webinars, CFD 101 educational resources, conference proceedings), a 12,441+ member LinkedIn users community, a quarterly newsletter, and a CFD-Online user forum. Customer evidence is heavily weighted toward academic users (IIT Dharwad, Northwestern, Oregon State, University of Ottawa, University of New Mexico, McMaster) while named enterprise adoption is thinner (HPD Design Consultants is the principal example). Revenue is not disclosed; the entity generates revenue through commercial software license sales, paid academic license extensions, and technical support services.
