Convergent Science releases CONVERGE 6 with automation and faster solvers

Convergent Science has launched CONVERGE 6, a major update to its CFD software that adds AI workflow support, broader GPU solver capabilities, and new tools for combustion modeling. The release is aimed at helping engineers run more complex simulations faster across industries including automotive, aerospace, energy, marine, and biomedical.

Why it matters: - CONVERGE 6 is designed to cut manual setup time and reduce simulation runtimes for engineering teams. - The update expands the kinds of physics and systems users can model, including combustion, turbines, compressors, junctions, and blood flow. - The new release matters for industries that rely on high-fidelity simulation to speed design and testing.

What happened: - Convergent Science released CONVERGE 6, a new major version of its CONVERGE CFD software. - The software adds more automation, improved efficiency, and broader modeling capabilities. - The release includes support for connecting AI models with CONVERGE Studio. - The company says users can access more information on the CONVERGE website.

The details: - CONVERGE 6 lets users connect AI models to the CONVERGE Studio interface. - A downloadable set of instructions lets AI agents handle pre- and post-processing tasks. - Those tasks include opening and modifying example cases, turning on different models, and plotting specific variables. - The GPU solver now supports compressible and incompressible flows. - The GPU solver also supports RANS and LES turbulence modeling. - The GPU solver supports detailed chemistry for combustion modeling on modern GPU architectures. - The upgraded Under-Relaxation Steady solver is built for faster convergence. - The URS solver is compatible with a variety of combustion models. - The URS update is aimed at steady-state simulations of industrial burners, flares, and gas turbines. - The 1D flow solver can now model turbines, compressors, and junctions. - The 1D solver supports a coupled 1D-3D approach that can reduce runtimes versus a fully 3D simulation. - The new Automatic Reaction Reduction and Optimization Workflow tool automates chemical mechanism reduction and tuning for combustion simulations. - CONVERGE Studio 6 includes C3MechV4.0.1 from the Computational Chemistry Consortium. - Users can extract fuel chemistry, reduce and optimize the mechanism, and run the combustion CFD simulation in one program.

Between the lines: - The release points to a push toward more AI-assisted simulation workflows, with automation extending beyond the solver itself and into model setup and analysis. - The addition of broader GPU and 1D capabilities suggests Convergent Science is trying to make high-end simulation more practical for faster iteration and larger problem sets. - Keith Richards, Co-Owner and Vice President of Convergent Science, said CONVERGE 6 expands and enhances models for automotive, aerospace, energy, marine, and biomedical applications. - Richards said the software is built to improve capability and accuracy for studies ranging from soot formation in IC engines to blood flow through the cardiovascular system.

What's next: - Engineers can now evaluate CONVERGE 6 for workflows that need faster setup, faster convergence, or more automation. - The new AI and mechanism-reduction tools may change how combustion simulation projects are prepared and run. - The software's expanded modeling scope could push adoption in more multi-physics and cross-industry applications.

The bottom line: - CONVERGE 6 is a feature-heavy update that combines AI-enabled automation with faster solvers and broader physics support to make complex CFD work more efficient.
