Altair HyperWorks CFD Solvers 2021.0

Altair HyperWorks CFD Solvers is a comprehensive portfolio of computational fluid dynamics technologies from Altair Engineering, Inc. Designed for accuracy, scalability, and fast turnaround, the suite unifies multiple solver technologies within the HyperWorks environment to address a broad range of flow and thermal challenges—from internal flows and heat transfer to external aerodynamics and complex free-surface behavior. Engineers in automotive, aerospace, energy, marine, and industrial equipment use these solvers to predict performance, guide design decisions, and accelerate product development.

Key capabilities include:

• General-purpose CFD: Robust steady and transient Navier–Stokes simulation with advanced turbulence modeling, conjugate heat transfer, rotating machinery, moving and deforming meshes, and multiphase options.
• External aerodynamics at scale: GPU-accelerated lattice Boltzmann technology for rapid transient vehicle and aircraft aerodynamics, enabling quick iteration on drag, lift, wake structures, and aeroacoustic indicators.
• Free-surface and multiphase flows: Smoothed particle hydrodynamics for sloshing, tank filling, lubrication, and gear churning, capturing complex interfaces without cumbersome meshing.
• Unified workflow: CAD-to-mesh setup, automated meshing, scalable HPC and cloud execution, and integrated post-processing for efficient, repeatable studies.
• Multiphysics and optimization: Co-simulation with motion and structural solvers for fluid–structure interaction and design exploration within the Altair HyperWorks ecosystem.

With its combination of solver depth, GPU acceleration, and an end-to-end workflow, Altair HyperWorks CFD Solvers helps teams reduce simulation time, improve fidelity, and deliver better designs faster.
