AERO Suite

Realistic multi-physics simulations thought to be unfeasible are now enabled by AERO at both ends of the computing spectrum: using high-fidelity computational models for maximum accuracy, and reduced-order computational models for maximum speed.  With AERO, CFD-based analysis of flutter, buffeting, trimming, maneuvering, acceleration, deceleration, aeroservoelastic control, aerothermal, aerothermoelastic, and many other fluid-structure and fluid-structure-thermal interaction problems can now be performed with unprecedented level of flow, structural, and thermal details, using the latest computational and HPC technologies.

The AERO Suite is based on results from two decades of research that have redefined the state-of-the-art of computational engineering and science, high performance computing, and model order reduction. Learn more.

AERO Modules

AERO-F   is a three-dimensional, compressible, Euler/Navier-Stokes, Arbitrary Lagrangian Eulerian (ALE), finite volume flow solver. It features state-of-the-art RANS, DES, and LES turbulence models. It operates on unstructured hybrid meshes that can be static, rigidly moved in time by a flow-driven motion of a six-degree-of-freedom rigid body, or deformed and possibly reconfigured by a movable surface. The meshes can also be simultaneously moved and deformed in time by a prescribed surface motion and/or deformation, or by coupling with the dynamics of a flexible structure computed by AERO-S. AERO-F can also perform linearized simulations for rapidly predicting the response of a flow to perturbations, and compute the sensitivity of output results to variations of shape and flow parameters. For flexible and/or thermal systems, AERO-F communicates with the structural/thermal analyzer AERO-S to perform coupled high-fidelity fluid-structure, fluid-thermal, and fluid-structure-thermal simulations.

AERO-S is a high-performance structural/thermal analyzer based on the finite element method. It is capable of  linear and nonlinear static, vibration (eigen), and dynamic analyses of restrained, partially restrained, and unrestrained homogeneous and composite structures. It features a comprehensive library of one-, two-, and three-dimensional finite elements for structural/thermal problems. It is also equipped for communication with the flow analyzer AERO-F to perform high-fidelity fluid-structure, fluid-thermal, and fluid-structure-thermal analyses. Learn more.

MATCHER is essential for the application of AERO-F and AERO-S to a multi-physics analysis. It enables these two computational modules to properly exchange aerodynamic, elastodynamic, and thermal data across non-matching discrete fluid/structure interfaces. Learn more.

SOWER is a pre- and post-processor for the computational modules AERO-F and AERO-S. It generates the appropriate binary input files needed for the (parallel) execution of these two modules. It also assembles the distributed binary output (result) files generated by AERO-F and/or AERO-S and converts them into the ASCII format for visualization purposes. Learn more.

AERO-I is a Graphical User Interface which simplifies and automates input preparation. It also organizes simulations into projects and folders, and enables data-reuse between different but related computations. It imports NASTRAN data files, and exports AERO results in the VisIt or XPost format. Learn more.

AERO-C provides the reliable solution to the ever increasing number of multi-physics problems faced by technology in general. Using this AERO module, one or more third party codes can be coupled to AERO-S, AERO-F, or both, via a provided C++ Application Programming Interface (API). Learn more.

AERO Packages

Four different AERO Packages are available. Each of them includes all of the AERO-F, AERO-S, MATCHER, SOWER, and AERO-I modules, but with different capability levels that address different technical needs.

Basic AERO Package [BAP].  This is the basic AERO package. Its capabilities are those marked with [BAP] in the descriptions of the individual capabilities of AERO-F, AERO-S, and their coupling. Essentially, this basic package is capable of standard linear structural/thermal analysis, all of AERO-F’s advanced inviscid  flow solution algorithms for a perfect gas and a rigid obstacle — whether this obstacle is fixed or set into a prescribed motion — and both steady and unsteady CFD-based aeroelastic analyses for divergence, flutter and other types of fluid-structure interaction applications.

Accelerated (Flows), Trimming and Maneuvering Package [ATMaP]. This is an optional upgrade for the Basic AERO Package. It adds to it: (a)  nonlinear structural capabilities, (b) capabilities for computing trimmed solutions of rigid and aeroelastic systems,  and (c) capabilities for computing the fluid dynamics and aeroelastic behavior of systems during acceleration or deceleration, landing, and maneuvering using dynamic control surfaces.

Linearized and ROM Package [LiROMP]. This is an optional upgrade for the Basic AERO Package. It adds to it the linearized and model order reduction capabilities for significantly speeding up inviscid flutter and other fluid-structure analyses, among others.

Viscous Package [ViP]. This is another optional upgrade package. It adds viscous laminar and turbulent modeling capabilities to BAP and ATMaP, and viscous laminar modeling capabilities to LiROMP. It also enables the solution of complex fluid-thermal and fluid-structure-thermal problems.
