Computational fluid dynamics (CFD) simulations have been and continue to be widely used by the aerospace industry to supplement wind tunnel and flight tests. They significantly reduce the cost and time of designing and analyzing aircraft. Although powerful, CFD tools can be complex, difficult to learn, and challenging to use effectively. In order to achieve reliable results, in-house best practices are created across several phases of the CFD process — from computer-aided design preparation and simulation to post-processing — using a wide variety of verification and validation cases. These best practices are then incorporated inside automated workflows to enhance productivity and market readiness.
This effort is considerable and not easily accessible to startups or small-sized companies. Moreover, as development of CFD technology continues, users who previously developed their own in-house best practices or workflows are no longer able to easily adopt new features or enhancements without going through high-level CFD training to become proficient with the new technology, and subsequently must reverify, revalidate or update their automated workflow.
To alleviate these challenges faced by the industry, Ansys has created Ansys Fluent Aero — an external aerodynamic project workspace targeted at the aerospace industry. Fluent Aero allows the user to automatically organize and explore a wide range of configurations and conditions (e.g., wind tunnel, natural flight, high altitude, etc.), using built-in, condition-dependent best practices to enhance accuracy and significantly reduce the amount of effort spent to create, maintain, and continuously update in-house CFD best practices and workflows.
Fluent Aero is a workspace that enables aerospace engineers to easily explore the aerodynamic performance of an aircraft under a wide range of flight regimes, without the additional general-purpose tools of the Fluent solver that aren’t typically useful for this type of study. This allows engineers to focus solely on their application without any additional capabilities or features that are unnecessary to their simulation, modeling, or results.
The workspace is subdivided into distinct views that guide the user through the creation of a matrix of conditions or design points, in which single and multiple parameters such as AoA, Mach, Reynolds, altitude, etc., can vary.
The main views within the Fluent Aero workspace include:
The project file organization provided by the Project View, the focused step-by-step workflow provided by the Outline View, and the tuned settings for external aerodynamics help engineers complete their CFD simulations more efficiently, enabling them to spend more time on their engineering goals.
The Fluent Aero workspace is available within the Fluent Launcher with an Enterprise license. Simply launch your Fluent software, select Enterprise, then select Aero. Click Start to launch the Fluent Aero workspace.
