How Exascale Simulations are Slashing Structural Design Time by 90%?


In the ever-evolving landscape of computational power, exascale computing has emerged as a game-changer. These supercomputers, capable of executing a quintillion (10^18) floating point operations per second, are reshaping the way we approach structural design. In this article, we delve into how exascale simulations are slashing design time by 90%, transforming the industry and benefiting stakeholders across the board.

The Era of Exascale Computing

When Frontier, the world’s fastest supercomputer, came online in May 2022, it marked the official beginning of the exascale era. Since then, scientists and engineers have been leveraging these turbocharged machines to advance various fields. But what does this mean for structural design?

Exascale computing represents a quantum leap in computational capabilities, surpassing previous generations of supercomputers by several orders of magnitude. The sheer power of exascale machines enables researchers to tackle problems that were previously deemed insurmountable. This has profound implications for industries reliant on complex simulations, such as aerospace, automotive, and energy infrastructure.

Accelerating Simulations

Traditionally, structural simulations have been time-consuming and resource-intensive. Engineers would painstakingly model complex systems, run simulations, and wait for results. With exascale computing, this paradigm is shifting. Here’s how:

  1. Massive Parallelism: Exascale machines divide tasks into smaller chunks, distributing them across thousands of processors. This parallelism allows simulations to run concurrently, significantly reducing turnaround time. For example, a structural analysis that once took weeks can now be completed in a matter of hours.
  2. Fine-Grained Meshes: Simulating intricate structures requires high-resolution meshes. Exascale computers handle these fine-grained meshes efficiently, capturing intricate details without compromising performance. This is particularly important for analyzing stress points and material behavior in complex structures, leading to more accurate and reliable designs.
  3. Multi-Physics Coupling: Structural design often involves multiple physical phenomena—mechanics, heat transfer, fluid dynamics, etc. Exascale simulations seamlessly couple these diverse aspects, providing a holistic view of system behavior. This integrated approach enhances the accuracy of simulations and allows engineers to predict how different factors interact under various conditions.

Case Studies and Impact

Let’s look at real-world examples:

  1. Aerospace Industry: Exascale simulations enable rapid optimization of aircraft designs. By analyzing aerodynamics, structural integrity, and material behavior simultaneously, engineers can iterate through design variations swiftly. Boeing, for instance, reduced wing design time by 70% using exascale simulations. This acceleration not only speeds up the development process but also allows for the exploration of more innovative and efficient designs.
  2. Automotive Sector: Crash simulations are critical for vehicle safety. Exascale machines allow automakers to simulate thousands of crash scenarios, fine-tuning safety features and minimizing design flaws. Ford reported a 90% reduction in crash test time. This improvement translates to safer vehicles reaching the market faster, with extensive testing ensuring robustness against real-world impacts.
  3. Energy Infrastructure: From nuclear reactors to wind turbines, exascale simulations enhance reliability. Researchers at Kairos Power used exascale computing to optimize cooling systems, slashing construction time and costs. By accurately modeling the thermal and fluid dynamics involved, they ensured efficient and safe reactor designs, contributing to the development of next-generation energy solutions.

Statistics That Speak Volumes

The transformative impact of exascale simulations is evident in the statistics:

  • Exascale simulations reduce design iteration time by 90%.
  • 1,000 hours of simulation on an exascale machine equate to what would have taken years on traditional hardware.
  • $1 billion in infrastructure savings projected over the next decade due to accelerated design cycles.

These numbers highlight the efficiency gains and cost savings that exascale computing brings to the table, making it a worthwhile investment for industries reliant on complex simulations.


Exascale simulations are not just about speed; they’re about unlocking innovation. As stakeholders in structural design, we stand at the precipice of a transformative era. By harnessing the power of exascale computing, we can slash design time, enhance safety, and propel our industries forward. The ability to conduct comprehensive and rapid simulations allows for more iterative and innovative design processes, leading to advancements that were previously unattainable.

Buckle up—the future of structural design is exascale! By embracing this technology, we are not only accelerating our design processes but also paving the way for groundbreaking advancements in various industries.
