How Cloud-Based & HPC Cluster Simulations Improve Product Design

These simulations are so large that high-performance computing (HPC) is required to process them in a reasonable amount of time. Leveraging cloud- or HPC-cluster-based solutions is gaining widespread acceptance as the best way to get optimal designs to market on schedule.

The automotive industry is a great example of this trend. Every year engineers have to produce cars that are faster, smarter, quieter, greener and stronger than previous models. As many of these are competing objectives, they require the use of large simulations to find an optimum that meets market demands. As a result, HPC clusters and cloud-based computing have become a staple in the industry.
 

Cloud and HPC Clusters Make Development Fast and Agile

As the cloud offers variable storage and computational resources, it enables users to quickly scale up or down simulation throughput and operational budgets. Instead of spending money on software licenses and HPC hardware, engineers can access the tools they need, as they need them, on a pay-per-use basis.

With the rise of data-heavy digital technologies —internet of things (IoT), digital twins and autonomous driving — and variable, unpredictable data loads, access to flexible computational resources is a necessity.

This unpredictability means that engineers may not have access to the software they will need. Fortunately, by consolidating computational resources and moving to the cloud, they can also consolidate their IT footprint. Instead of installing programs on individual computers, they can use software already installed on a central system. This affords them software access from anywhere around the world.
 

Implementation Challenges to Cloud-Based Simulation Solutions

Despite the benefits, implementing the cloud can be a challenge. Implementations traditionally involve designing job scheduling, user interface and storage systems. If engineers were to implement the cloud themselves, they could experience considerable downtime, productivity loss and expenses.

ANSYS Cloud instantly offers engineers access to computational resources.

Engineers need a turnkey HPC cluster solution that is ready when they need it. The solution will have to enable the shifting of simulation jobs off local machines — to a central computational resource either on premises or in the cloud. It will also need to reduce the time and cost of implementation. Three solution examples include:

1. Ansys Cloud: Offers easy access to on-demand HPC in the Microsoft Azure cloud computing platform, from within Ansys Mechanical, Ansys Fluent and Ansys Electronics Desktop
2. HPC Cluster Appliance Solutions: Provide an out-of-the-box, plug-and-simulate HPC cluster that is internally or externally managed. The cluster is also preconfigured and optimized for Ansys simulation and job management software
3. Cloud-Hosting Partners: Offer outsourced IT and computational resources
