Altair Flux 2021.1.0

Altair, a global technology company providing solutions in simulation, high-performance computing (HPC), and artificial intelligence (AI) announces the release of its latest simulation solutions, including comprehensive computational fluid dynamics (CFD) and expanded capabilities in electronic system design (ESD). Updates include all major CFD solutions under a single license, expanded end-to-end electronic system design capability, and seamless access to the cloud.

Unparalleled breadth of CFD solutions under a single license

Altair CFD is a cost-effective alternative to purchasing individual tools from multiple software vendors by delivering all major CFD solutions under a single license including:

- General purpose fluid dynamics and thermal simulation leveraging the Navier-Stokes (NS) method
- Simulation of oiling, sloshing and mixing with smoothed-particle hydrodynamics (SPH)
- External aerodynamics simulation using the Lattice Boltzmann method (LBM)
- Simulation of particle fluid systems with the discrete element modeling (DEM) method
- Modeling of complex, integrated thermo-fluid systems leveraging Altair’s unique system modeling technology

This ensures engineering teams always have the most appropriate technology available for each application, reducing modeling and product development times. Altair CFD provides advanced capabilities including coupling between several different CFD applications as well as with other applications such as structural analysis, etc.

Additionally, the LBM and SPH codes in Altair CFD were written from the ground up using native graphics processing unit (GPU) codes, enabling faster simulations, more design exploration, and improved product performance.

Expanded end-to-end electronic system design capabilities

Altair’s electronic system design toolset has a new thermal management workflow to enhance the design of electronic devices. In addition to the existing Altair SimLab workflows for structural stress, vibration, and drop-test performance, product engineers can now ensure the cooling of printed circuit boards (PCBs) and complete systems to prevent overheating, product reliability issues, or expensive late-stage redesigns.

Smart connected devices increasingly need high-speed memory. Altair PollEx has added signal integrity automation for double-data rate (DDR) memory interfaces, enhancing optimization of DDRx timing, transmission lines, topology, and terminations. Other improvements include additional power integrity simulation and the capability to export PCB layers for thermal management analysis. For more information about the latest enhancements to Altair’s ESD solutions, register for the upcoming “Modern Electronic System Design Webinar Series.”

Zero-download simulation in the cloud with Altair One

Altair One is a single portal for Altair’s products, accessible anywhere via standard workstations, PCs, laptops, and mobile devices. Users can launch simulation applications in the cloud from a single interface with easy access to resources that are on-premises, in the cloud, or a hybrid. Product teams can increase simulation-driven design collaboration by securely uploading, accessing, storing, and managing data using the Altair One drive.

Altair One does not require additional capital expenditures on complex IT and can scale immediately in response to peaks in workload. It also empowers users to provision turnkey, scalable appliance clusters across all major cloud providers including Amazon AWS, Microsoft Azure, Oracle Cloud Infrastructure, and Google Cloud Platform.

Flexibility is further enhanced by Altair Units, Altair’s patented, subscription-based licensing model, which allows organizations to pay only for what their employees need, when they need it. This includes the new Product Engineer bundle that automates and simplifies complex analysis tasks for multiple physics.

Altair Flux 2021.1 Release Notes

A full detailed list of all new features as well as improvements and fixes is available in theAltair_Flux_2021.1_Release_Notes.



Altair Flux, a low frequency electromagnetic simulation software used for motor simulation captures the complexity of electromechanical equipment to optimize their performance, efficiency, dimensions, cost or weight with precision, bringing better innovation and value products to end users.

Altair Flux also gives researchers rare insights into the working and performance of motors and offers a simple user-friendly platform to seamlessly simulate and soft test motors to obtain credible results in the shortest possible time.

Flux simulates magneto static, steady-state and transient conditions, along with electrical and thermal properties. With strong coupling to the Altair HyperWorks multiphysics optimization platform, Flux evaluates subsystems’ dynamic interactions and streamlines the entire design process.

Altair Flux 2021.1 accelerates motors, sensors, and actuators design thanks to a new method to compute current density in child conductor regions in 3D, with relaxed geometry constrains.
