Altair updates include comprehensive computational fluid dynamics and electronic system design tools

Altair has announced 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.



“Throughout our 35-year history, Altair has developed and acquired countless specialized technologies to solve even the most challenging CFD problems,” said James R. Scapa, founder and chief executive officer, Altair. “We are proud to have the industry’s most robust CFD offering whose breadth and depth is unparalleled and can efficiently and effectively address a broad range of multidisciplinary challenges.”


Altair says its 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 modelling (DEM) method

  • Modelling of complex, integrated thermo-fluid systems leveraging Altair’s unique system modelling technology

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 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.


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.


The supplier says its 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.
