GE and Altair announce software partnership

Altair and GE have signed a multi-year software agreement making Altair the exclusive distributor for GE’s Flow Simulator software. Flow Simulator is an engine system modelling software which provides functionality for numerous tools for fluid systems to enable multi-disciplinary analyses.

Altair will leverage its expertise in commercial software deployment and support, broad industry domain knowledge, and global footprint to expand the technology’s adoption.

‘We are very excited to work with Altair Engineering to commercialise our Flow Simulator software, a GE state-of-the-art engine system modelling tool,’ said Gary Mercer, vice president and general manager of Engineering for GE Aviation. ‘This software helped guide GE to design world record efficient gas turbines and the more advanced aircraft engines in the industry.’

Developed internally by GE with a modern Graphics User Interface (GUI), GE’s Flow Simulator is a multi-grid based solver.  It uses the continuity-based Newton-Raphson method, encompassing several numerical techniques that conquer the robustness issues of stiff fluid system designs. It currently serves more than 1,500 users as a single-fluid system modelling tool across the aerothermal and combustion engineering design communities at GE.

‘Flow Simulator’s mixed fidelity simulation capabilities for engine systems fill an important gap to help improve design processes and reduce development, manufacturing and operational costs for many organisations. It is a welcome addition to Altair’s strong multiphysics system modelling portfolio,’ said Dr Uwe Schramm, chief technical officer at Altair.
