2015 SmartDO Conference for Smart Computing and Design Optimization at Taiwan

2015 SmartDO Conference for Smart Computing and Design Optimization at Taiwan, Nov. 26, Hsinchu Headquarters of National Center for High-performance Computing, Hsinchu City. Hosted by SmartDO developer FEA-Opt Technology Co. Ltd., the 2015 conference will be co-hosted by the National Center for High-performance Computing (NCHC) and the Academia Industry Alliance for Noise, Vibration and Harshness (AITA/NVH).

Optimizing the remote sensing instrument of Taiwan’s FORMOSAT-8 satellite

Taiwan began designing and developing its first satellite in 1994 in collaboration with a U.S. space systems contractor. FORMOSAT-1 was launched in January 1999 and provided service until its retirement in 2004. FORMOSAT-2 was launched later in 2004, followed by FORMOSAT-3 in 2006. In 2010, FORMOSAT-5 passed design verification and now awaits deployment. FORMOSAT-5 will carry the first optical remote sensing instrument payload completely designed and developed by Taiwan itself.

Today FORMOSAT-8 is under development. This new satellite will inherit the experience from FORMOSAT-5 and will likewise carry an optical remote sensing instrument developed by Taiwan. Opto-mechanical systems integration will be led by the country’s Instrument Technology Research Center, with participation by the Opto-Mechanical Design Analysis (OMDA) Lab supervised by Professor Yi-Cheng Chen at Taiwan’s National Central University, which is responsible for weight reduction of the mirror supporting structure. To achieve the breakthrough improvements required in structural weight, the OMDA Lab is utilizing FEA-Opt Technology’s SmartDO design optimization, system integration and process automation software.

Aerodynamic and structural optimization of a turbofan

Optimizing turbofan designs is challenging because of the need to deal with both aerodynamic and structural performance. While designing a fan with high performance and efficiency is important, strength and reliability of the structure are also critical. Further, integrating parametric CAD, CFD and stress analysis is not a trivial task and usually takes extensive effort.

In this project SmartDO and ANSYS were utilized together to optimize a turbofan. The technical services team at SmartDO’s developer, FEA-Opt Technology, helped the customer build a parametric model with ANSYS DesignModeler, construct the CFX and mechanical analysis block, and integrate SmartDO with ANSYS Workbench. SmartDO was able to increase the mass flow of the fan by almost 14% while slightly reducing the maximum stress under aerodynamic and structural loading. These results showed promising possibilities for further design development. Continue reading

After 2013 saw Red Cedar Technology acquired by CD-adapco and FE-DESIGN by Dassault Systèmes, mergers and acquisitions in the design exploration and optimization software industry took a breather last year. What could drive M&A activity in 2015? Continue reading

Design exploration vs. design optimization

Automating the search for solutions to engineering problems can take either of two broad approaches: design exploration or design optimization. Practitioners making technology choices need to understand which tools do one, which do the other, and which approach best fits their needs. A global roster of commercially available design exploration and optimization software appears at the end of this post. Continue reading
