Topology Optimization Considering Fluid Flows

For the past three decades, Altair’s optimization solutions have driven the innovative, lightweight, and structurally efficient designs of many products you see and use every day. The intense focus on additive manufacturing in recent years have given a boost to topology optimization and generative design, providing more freedom to explore alternatives. Today, we keep on innovating the technology, looking at including multiple physics, like thermal, electromagnetics, and fluid flow to drive design. Altair AcuSolve – coupled with Altair Optistruct – enables engineers to find the optimum shape by simply defining inlets, outlets, and the allowable space in which the solver can work. AcuSolve’s gradient-based topology optimization method will quickly and efficiently find the path of least resistance to deliver fluid flows with minimal effort.

Fly High with Optimization - Optimizing Camcopter® S-100 Design at Schiebel

Unmanned aerial systems (UAS) are a rapidly evolving technology and used for a variety of civil and military purposes. To ensure airworthiness, UAS manufacturers rely on advanced simulation and manufacturing techniques to create efficient designs. Aerial systems active throughout Europe and operating with diverse payloads for different missions require a reliable vehicle architecture and fuel supply. To ensure perfectly tuned architecture and a lightweight design while increasing stiffness and strength, Schiebel used Altair solutions in combination with 3D printing. The engineers performed various simulations to optimize the design of AM engine parts. Using Altair’s topology optimization structural design tool, Schiebel reduced the weight significantly while maintaining high stiffness. Subsequently, the system was evaluated by laminar and turbulent flow simulation as well as conjugate heat transfer simulation using Altair CFD™. Contacts, NLFE and complex dynamic systems were modeled with Altair® MotionView® and Altair® MotionSolve®. Schiebel also took advantage of APA solutions.

Reducing Risk of Failure of noise compliance with direct fan noise simulation

This presentation shows how advanced simulation technology can provide a cost effective way to minimizing the risk breaching noise regulations. Often the issue is only found out in a prototype testing scenario, bench test results can give misleading information as acoustic character of a rotating component will change in an installed condition. Altair CFD brings a solution to the market for installed fan acoustics by directly calculating the convective field, this virtual method can significantly reduce risk of failure leading to development cost savings and mitigation of timeline overshoot.
