Trends in (Computer-Aided) Engineering Driving HPC Innovation

Last Friday, I gave a keynote talk at HP-CAST18 in Hamburg, Germany, about the trends in engineering that are driving HPC innovation. It was my first time joining HP’s worldwide HPC User Group Conference, and I was particularly impressed by HP’s detailed roadmap for new platforms, storage systems and low-energy computing, as well as their progress towards exascale computing.

I felt honored to be invited to speak in front of HP executives, HP technical staff, industry analysts, HP customers and partners. It’s a sign that HP seriously takes into account input from ISVs (independent software vendors, like ANSYS). Basically, my presentation identified some major challenges and trends in (computer-aided) engineering that are driving the demand for more HPC software innovations. Continue reading

Durability and Reliability for Sea-Floor Oil and Gas Processing Equipment

Developing more efficient water processing units for oil and gas production is becoming an industry focus. Water occurs naturally within oil and gas reserves and can also be introduced as part of enhanced oil and gas recovery process. The water involved in oil and gas production is called produced water and is an undesired by-product in that industry. Both onshore and offshore produced water requires large amounts of pumping energy and the costs for water management and disposal are rising.  The problem is greatest for old wells and for offshore production. Exciting new technologies are being developed to address these issues and engineering simulation can help.

Multi-Configuration in ANSYS CFX: Automatically Initializing a Transient Simulation from a Steady-State Simulation

In reality, most fluid mechanics problems are unsteady in nature. Steady-state approximations have been used since the advent of CFD as they provide adequate accuracy in many cases while the computational demands are quite moderate compared to a full transient, unsteady simulation. Current advances in multi-core desktop workstations and accessibility to high performance computing clusters allow CFD engineers to simulate larger problems with more detailed physics than ever before. This has allowed CFD engineers to increase the fidelity of their simulations by modeling the unsteady, transient nature of the flow.

Typically when running a transient simulation, best practices would dictate use of a a steady-state simulation as an initial guess. In the past this would require you to run two separate simulations, one steady state and one transient.  In ANSYS CFX software, it is now possible to do both in a single simulation by using a multi-configuration setup.

Recognizing the Business Benefits of HPC

In Volume 5, Issue 3 of the ANSYS Advantage we highlighted leading organizations that are benefiting from combining high-performance computing (HPC) environments and ANSYS solutions to create large, high-fidelity simulations that would not have been possible a few years ago. Continue reading

Viva La Digital Revolution!

We are at the middle of the Digital Revolution, which requires a process and cultural change to design products and processes. While some companies are ahead of the curve because they are in the right industry or right location or have the right management team, most organizations are feeling something is changing and they need to adapt. But many don’t know which strategy to adopt to maintain leadership. Continue reading
