Nvidia helps Ansys deliver GPU-accelerated CFD Fluent solver

Nvidia Tesla GPUs can be found in servers, clusters and workstations

Users of Ansys Fluent 15.0 users can now use Nvidia graphics processing units (GPUs) alongside CPUs to speed up fluid dynamics simulation. The jointly developed computational fluid dynamics (CFD) solver now joins Ansys Mechanical in the simulation specialist’s growing family of GPU-accelerated applications.

One customer taking advantage of this new solver is Parametric Solutions Inc, which specialises in the design, manufacture, test and assembly of gas turbine components and modules.
“By adding Nvidia GPU accelerators, our engineers cut the time for typical Ansys Mechanical models in half, doubled the performance of maxed out CPU systems and often saved an entire day’s worth of work,” said David Cusano, chief technology officer and vice president of Parametric Solutions Inc. “Now, with support for GPU acceleration in Ansys Fluent 15.0, complex CFD simulations can be accelerated in a similar fashion, especially when paired with new, higher performance Nvidia Tesla K40 GPU accelerators.”

Nvidia GPU accelerators don’t come cheap. The price of an Nvidia Tesla K40 is over £4,500. But in addition to the performance benefits, users can also save on software costs. With Ansys software, for example, each GPU socket is treated the same as a single CPU core with respect to license requirements.

We will be taking a closer look at the Nvidia Tesla K40 in the coming months and testing it out with Ansys simulation software.
