Making Optimization a Shared Experience
Enterprise Suite allows teams to build the advanced multidisciplinary optimization workflows that are critical to complex system design.
Published on “Desktop Engineering“
No longer an oddity or curious interloper, wind turbines are settling in as a familiar part of both urban and rural landscapes. Yet beneath their simple and majestic stature belies a design complexity that tests even the most technically astute engineering organizations.
Just ask AirWorks, a contractor for advanced projects in the space and defense
industries, which is refining a long-term strategy for wind energy with a pilot project for wind turbine rotor blade design. To ensure a proper concept for a certified rotor blade, the Airworks team needs to balance a variety of multidisciplinary optimizations (MDOs) — for example, creating models that couple aero-structural blade properties with wind flows and possible failure scenarios — in addition to performing stability analysis and evaluating materials and manufacturing time costs.
On top of the sheer complexity of the blade design, there is the collaborative nature of the engineering process. It’s made all the more challenging given that AirWorks’ aerodynamics, load and mold design experts are based in Rome, and the system-level architecture, structure, manufacturing and project management domain experts reside more than 400 miles away in Trieste, Italy.
“When a wind energy project launches, we always have problems,” admits Stefano Picinich, Airworks’ founder and managing director. “Normally, we move three or four key people from Rome to Trieste for a couple of months to enable a smooth design start, but this took engineers away from routine support, which was far more costly.”
The solution to both the design complexity and collaboration problem arrived in the form of Enterprise Suite, a new platform from ESTECO, which aims to simplify some of the challenges around MDO and multi-objective optimization.
Launched mid-year, Enterprise Suite combines the advanced capabilities of the modeFRONTIER 4.5 multi-objective and MDO platform, with SOMO, ESTECO’s new framework for distributed execution and collaboration. The duo is designed to give engineering groups better control over the design of complex systems by helping them more effectively organize and manage critical simulation data — all while allowing a dispersed and varied team of domain experts and optimization and integration specialists to join forces to build advanced MDO workflows.
The Power of the Web
Key to the pair’s power is a complete redesign that extends the modeFRONTIER desktop paradigm to a Web-based collaborative environment. The new approach means that multiple users, with different competencies and located at different sites, can more easily participate in the MDO process. They can share models and optimization strategies via a shared repository that can be accessed anywhere, anytime, with only a Web browser.
SOMO’s Dashboard page lets users find More Information about their work, as well as direct links to the most recent resources.
“Today, all companies are working in scenarios where different people work together; there are few instances of single engineers doing all the work on their own from design to detailed modeling,” notes Matteo Nicolich, ESTECO’s product manager for SOMO. “Rather, you have different groups with different expertise working together, and they need a tool to integrate the different levels of knowledge in the same environment. The Web provides the classic answer for this type of framework.”
Consider a scenario where an aerodynamics specialist and a structural expert need to collaborate on the same design, but are located in different venues. They’re performing their individual modeling and optimization routines using siloed tools and with very disconnected workflows. Traditionally, these two would have to manually trade their different model files to work together — raising the risk of one party being saddled with incomplete data if a particular type of simulation or MDO changed along the way. Moreover, domain experts unfamiliar with how to create specific design of experiments (DOE) or optimization strategies in modeFRONTIER were shut out of the workflow, unable to contribute models to the greater cause or to reuse other experts’ MDO work because it was not easily accessible.
Users can organize their work and data inside the SOMO shared repository using projects and workspaces. Users associate projects with one or more workspaces to control how project resources are shared among other users.
With Enterprise Suite’s Web-based approach, however, project experts can participate in MDOs without knowing the details of that other discipline, and without the skills to create the integration and workflows. Moreover, by storing specialists’ optimization and design space exploration strategies in a single, structured database, companies protect their intellectual property, nurture a shared knowledgebase, and promote MDO reuse.
While the ability to share optimization plans is intriguing, SOMO’s potential to facilitate collaboration and help multidisciplinary engineering teams easily create and modify optimization workflows is its strongest selling point, according to Marc Halpern, Ph.D., research vice president at Gartner. Workflow is generally difficult to change in typical product data management (PDM), product lifecycle management (PLM), and service lifecycle management (SLM) offerings, Halpern says, so SOMO’s “flexibility of workflow and collaboration functionality will be key to its acceptance.”
Freedom to Innovate
Enterprise Suite also delivers innovations in the areas of distributed execution and post-processing analysis capabilities. With simulation and optimization continually hungry for additional compute power, ESTECO designed SOMO to support high-performance computing (HPC) systems and cloud environments so engineering groups can easily add more horsepower when needed.
With SOMO, users can create a DOE or optimization plan for a given project, while having direct visibility to the most meaningful More Information from the generated session.
In addition, SOMO will automatically execute simulations and optimizations across a number of nodes in a distributed fashion. It’s a process that is transparent to the user, thereby reducing the burden on IT, Nicolich says. Users can select where they want their task to be executed based on their role and privileges, or the software will automatically queue up and distribute jobs based on the requirements of the software, as well as the availability of computing resources.
On the post-processing front, Enterprise Suite is stocked with an array of tools, including new data visualization capabilities and statistical analysis reports to help domain experts and other engineering collaborators make sense of the DOE and optimization findings. Because the Web-based system supports HTML5, users can access the charts and report capabilities on an array of devices, from laptops to tablets.

While Airworks is still getting its feet wet with Enterprise Suite’s new capabilities, Picinich says the Web-based interfaces align perfectly with the firm’s working style and is likely to make the collaboration process a lot easier. More to the point, though, he sees Enterprise Suite opening doors to new design innovations, whether related to wind turbine blade design or in Airworks’ other core areas of focus.
“The platform gives our people the freedom to think about how to improve the product, rather than occupy their minds with issues that have more to do with logistics like relocating from one office to another or checking an FTP for new data,” he explains.
Nevertheless, even the best engineering tools can’t cover for a lack of design expertise and well-defined goals, he cautions. “Sharing optimization data, accessing HPC resources, and having a smarter, faster platform doesn’t mean people can relax on the engineering side,” he says. “Tools only provide a link between your expertise and your ideas for the product you design.”
