Altair Flow Simulator is a 3D design tool that provides interdisciplinary modeling and optimization for fluid and thermal systems within a CAD-integrated environment. Flow Simulator was originally developed by GE Aviation to simulate challenging gas turbine applications like the secondary air systems, oil & lube systems, combustor cooling, and thermal management of accessories. Today, Altair Flow Simulator leverages these modeling capabilities to support all thermal systems, including those crucial to electromobility, renewable energy and electronics design.
