Our paper entitled "Topology optimization in OpenMDAO" by H. Chung, J.T. Hwang, J.S. Gray, and H.A. Kim (2019), has been published on the journal of Structural and Multidisciplinary Optimization (SAMO). In this paper, we present a modular paradigm for topology optimization using OpenMDAO, an open-source computational framework for multidisciplinary design optimization. This provides more accessible topology optimization algorithms that can be non-intrusively modified and easily understood, making them suitable as educational and research tools.

The use of 3D printing, also known as Additive Manufacturing (AM), has moved well beyond prototyping, rapid tooling and toys; it is considered a production tool. As these advanced manufacturing techniques enable complex and revolutionizing structures and material with intricate details that were not possible before, topology optimization is considered the ideal design method to produce such innovative and unintuitive designs for AM. This course will provide a practical understanding of topology optimization and additive manufacturing. It will uncover the numerical machineries of a range of topology optimization methods and reveal how to formulate design problems and select numerical parameters to yield successful designs. It will also discuss the state-of-the-art topology optimization capabilities in the context of material and structural designs under multiphysics. The course will also offer an overview of rapidly developing additive manufacturing technologies, including those commercially available as well as the state-of-the-art methods for the future. It will discuss the material types and capabilities for each method and the associated considerations for design, both at material and structural scales. The course will also include a practical hands-on element using an open source topology optimization code.

The 2018 AIAA Aviation Forum was held in Atlanta, USA from 25 June to 29 June, 2018. The M2DO lab presented during the Multidisciplinary Analysis and Optimization Conference on the following subjects:
Springer recently accompanied the USNCTAM18 committee and the Female Researchers Chapter (FRC) of the International Association for Computational Mechanics (IACM) in the opening of the National Congress of Theoretical and Applied Mechanics (USNCTAM18) in Chicago. The event comprised 56 researchers from various universities and research institutes who gathered to share their experiences. Professor Kim, the Chair of IACM-FRC, introduced the purpose of the event, the mission of IACM-FRC and ran the event as moderator. The event began with a reception catering and ended with lively discussions.

Our journal article titled "Stress and Strain Control via Level Set Topology Optimization" has been accepted for publication in Structural and Multidisciplinary Optimization. The work presents a level set topology optimization method for the manipulation of the stress and strain within structures.
Our article titled "Structural Optimization of Plate-Like Aircraft Wings under Flutter & Divergence Constraints" has been accepted for publication in the AIAA Journal. The work focuses on weight minimization of wing structures via plate thickness distribution, with constraints on aeroelastic stability.
Professor Kim has been invited to visit the US Air Force Academy in Colorado Springs, CO to give a lecture to the cadets on aerospace design with optimization and a seminar on multiscale and multiphysics topology optimization. The visit is scheduled for 3 November 2017.
3D printed parts can be lighter but stronger. How will these parts perform in the harshest environments 1, 2, 3, or 4+ years down the road? Such will be the topic of a panel discussion to be attended by Prof. Kim as part of the 5th Additive Aerospace Summit, to be held in Los Angeles, October 18 - 20.
The first ECCOMAS Thematic Conference on Simulation for Additive Manufacturing was held on 11-13 October 2017 in Munich, Germany. The event gathered researchers to exchange ideas on multiscale and multiscale issues, material modelling and simulation, and shape & topology optimization related to additive manufacturing. Xiaoyi Zhou gave a presentation entitled ‘A shape morphing technique for continuous variation of microstructures in multiscale structural topology optimization’.
The M2DO group has been invited to give two presentations at the upcoming CAE geometry workshop: One an overview of our lab’s research on level set topology optimization, the other on critical challenges in multiscale topology optimization, i.e. connectivity issues. The workshop will be held in Cambridge University on 14-15 September, and was organized by ITI Global to exchange ideas regarding the latest challenges in CAE geometry and meshing with technologists in industries, academics in universities and vendors.
On September 27th, Professor Kim has been invited to give a seminar entitled "Topology Optimization for Multiscale and Multiphysics Design" at the applied mathematics department of UC Berkeley. The presentation will introduce some of the latest developments in topology optimization, including advances in stress-constrained design as well as multiscale design optimization: breaking down the barrier between material and structural designs. The latest efforts in topology optimization for multidisciplinary design problems, i.e. aeroelastic wing, will also be discussed; such complex multiphysics, multifunctional structures may be too complex to rely on designers’ intuition. The presentation will end with the vision for future engineering design where complex coupled multiscale and multifunctional system designs are assisted and enabled by topology optimization.

Professor Kim organised a two-session minisymposium at WCCM XII which attracted interesting, high-quality papers. Some of the discussion topics included:
Professor Kim recently instigated new fellowship awards for female early career researchers which were recognized at the award ceremony during WCCM XII.
Professor Kim also organized a female researchers forum on Tuesday 26 July, whereby 40 female researchers in computational mechanics at all stages in their career got together for a panel discussion and networking event, sponsored by Elsevier. These female researchers initiatives led to establishing a female researchers in computational mechanics chapter in the International Association of Computational Mechanics.
