Editor’s Pick: CFD in the Cloud

Tony LockwoodDear DE Reader:

If you have your consultant’s shingle out or if you work at a tight-budgeted joint, you always seem to need more tools and resources. Then again, even big outfits need burst horsepower to handle complex simulations. This is where the cloud is really putting the oomph into the gig economy and engineering workflows. If CFD (computational fluid dynamics) is a tool you crave or need more power to run, today’s Editor’s Pick of the Week has your name on it.

Envenio recently announced that its EXN/Aero end-to-end CFD solution is now hosted on the Google Cloud platform. This, they say, is a “cash flow friendly” way to access high-performance CFD resources on a pay-by-the-month basis. Subscriptions start at $250 a month for on-demand access and include 500GB of storage, technical support and training. Training doesn’t look like it will require much if you’re familiar with CFD systems.

Anyway, from your browser, you access EXN/Aero’s solver and its meshing and post-processing tools. Meshing uses the Pointwise engine. It has automated meshing capabilities, and hybrid structured/unstructured mesh topology is supported. You can use your own post-processor if you prefer. EXN/Aero has an assortment of on-demand compute options, enabling you to scale your simulations on the fly.

At a Glance: EXN/Aero

  • End-to-end CFD solution now hosted on the Google Cloud.
  • Automated meshing capabilities; supports hybrid structured/unstructured mesh topology.
  • Provides multiple solver models, including LES, RANS, heat, ideal gas and high speed and compressible flow.
  • Supports CGNS database input; supports CGNS and VTK data outputs.
  • Monthly subscription model for on-demand access; includes 500GB of storage, technical support and training.
  • Live demonstration available.

The EXN/Aero solver has a slew of models you can work with starting with LES/DES, RANS and SST-RANS. You can do steady and unsteady turbulent flow calculations. It solves for compressible flows and buoyancy-driven flows as well as heat and conjugate transfers. Porous media, multiphase particle transport and passive scalar transport are some others. The EXN/Aero engine leverages NVIDIA GPUs (graphics processing units) and Intel CPU resources, so runs should be speedy.

Basically, how it works is that you feed EXN/Aero geometry or mesh files as input, set up your job and hit submit. Under the Platform tab on the Envenio website is one called User Manual that covers all this. Not gated. Interesting read. Aside: Under that Platform tab, CFD mavens will get into perusing another read called Theory Manual as well as working through the articles under the Use Cases and Validation tabs. Envenio did some excellent work on this material.

EXN/Aero sounds like good stuff. It could be the toolset or the horsepower extension you’ve been thinking about. You can set up a live demo to check EXN/Aero out for yourself. For now, hit today’s link and start learning more.

Thanks, Pal. – Lockwood
