Convergent Science

Convergent Science is a computational fluid dynamics (CFD) software company headquartered on Enterprise Lane in Madison, Wisconsin. Its co-founders were graduate students at the University of Wisconsin-Madison in 1997, and the company grew from a single small office to a multi-physics platform with users in industry, academia and government worldwide. Its flagship product, CONVERGE, is CFD software with autonomous meshing that removes the grid generation step from the simulation process, so engineers can explore design options quickly, predict problem areas before manufacturing and optimise products.

CONVERGE capabilities

• Autonomous meshing with Adaptive Mesh Refinement (AMR), which refines the mesh only where the flow needs it
• Detailed chemistry solver with adaptive zoning for reacting flows
• Large eddy simulation (LES) turbulence modelling and a density-based solver with non-reflective boundary conditions for combustion instability studies
• Spray modelling with Lagrangian, Eulerian and coupled VOF-spray approaches for liquid-fuelled aviation and power gas turbines
• Hydrogen modelling for aerospace, energy and storage applications
• CONVERGE Horizon and Explore tools, and partnerships with Intel, Rescale, Tecplot and Gamma Technologies

Aerospace and propulsion applications

The gas turbine application pages describe simulations of lean blow-off for Jet-A and alternative jet fuels, flame flashback in hydrogen and methane swirl burners, flame arrestor placement for hydrogen fuel, and thermoacoustic combustion instabilities in ramjets, scramjets, rocket engines, afterburners and gas turbines. Other application areas include burners, compressors, fans and blowers, exhaust aftertreatment, e-mobility, biomedical and general flow.

Training and events

Convergent Science runs free CONVERGE webinars on CFD methods and the role of AI in simulation, hands-on training courses on case setup and modelling options, and publishes technical blog posts, such as modelling elbow erosion and performance on the latest Intel CPUs.

Shows

Convergent Science appears in the exhibitor lists of the Small Satellite Conference 2027, Space Tech Expo Europe 2026 and the AIAA SciTech Forum 2027.
