The world’s energy industries are continuously adapting to the changing market and consumers’ demands for cheaper, safer, cleaner and more reliable fuel sources. Altair has a wide variety of technology, multi-faceted experience and resources to help our customers build and maintain solutions that provide a competitive advantage in their particular areas of expertise.

Three primary factors are at the core of Altair’s impact on the Energy Industry:

  • The rise of HPC and its near-universal availability, not just for large, established players, but also to small/medium-sized businesses

  • The rapidly-shrinking development schedule and budget for everything from down-hole tools to carbon-fiber turbine blades

  • The competitive advantages afforded by Computer-Aided Engineering (CAE) simulation and optimization

Altair makes the leap from supplier to Partner by providing a combination of world-class PBS Works technology for Enterprise Computing, an expert ProductDesign engineering organization with experience in practically every industry domain and unmatched modeling, simulation and optimization tools in HyperWorks.

Some examples of where we’ve made game-changing innovations with our Partners are:

  • Oil and Gas: mechanical earth modeling, subsea equipment optimization and offshore platform design

  • Wind: composite blade optimization, turbine assembly analysis, wind farm performance

  • Turbine: high-fidelity turbine modeling, thermal management, blade out containment

  • Solar: tracking system optimization, thermal performance analysis

  • Nuclear: nuclear reactor safety, thermal hydraulics and process optimization

Altair HyperWorks provides a comprehensive suite of CAE tools to solve energy discovery, extraction and utilization problems throughout the energy industry.

“The simulation process accelerated our product development to 26 months from the previous 65 months,
a 60 percent reduction in overall development time. Furthermore, the process reduced overall development costs.”

Oil and Gas

Altair’s tools and expertise are being used by the world’s largest and most innovative Oil and Gas companies to discover more efficient ways to meet the world's growing energy needs while addressing expectations of economic and environmental responsibility. This includes improving the production and performance of existing fields as well as discovering, evaluating and developing new ones. Customers are using our solutions to solve engineering problems in onshore, offshore, HPHT, ultra-deepwater and arctic applications.

Altair’s most prominent contributions include:

  • Mechanical Earth Modeling: Leveraging finite element analysis (FEA), uncertainty analysis and optimization techniques in HyperWorks, engineers and scientists are able to characterize and predict how rock formations like strata and fault lines will react to drilling and extraction before production even begins. Augmented by direct connectivity to HPC resources both locally and in the cloud, HyperWorks is the premier platform for solving multi-disciplinary modeling, analysis and optimization challenges for structural geology.

  • Offshore and Subsea Equipment: From optimizing down-hole tools to extending fatigue life of subsea equipment to reducing LNG sloshing, Altair has a strong reputation of repeatedly enabling successful execution of offshore projects. Mechanical optimization plays a large part in that portfolio, as does our unmatched Fluid-Structure Interaction (FSI) solutions for equipment, risers, platforms and pipelines.

  • HPC Resource Management: As traditional and accelerated resources have become more available both traditionally and in the cloud, Altair’s integrated approach to all things HPC has brought science and engineering to the forefront of technical capability. This includes the traditional fields of seismic processing and reservoir simulation, but increasingly includes all areas of engineering looking to leverage the advantages of HPC through remote visualization, web portal integration and parallel processing for uncertainty analysis and optimization.

  • Big Data Analytics in Energy & Utilities: Utility organizations must be able to analyze and interpret large volumes of data, quickly and efficiently in order to meet today's business challenges, such as green-energy mandates, regulatory compliance, tight control on infrastructure assets, high-level customer service and smart-grid initiatives. Envision allows easy customer billing analysis, meter data aggregation, rate schedule simulation & optimization, assets and outage management, and more.
