ANSYS R18 Update: Fluids

Title: ANSYS R18 Update: Fluids Bill. Hi everybody and thanks for joining me today. I'm Bill Culp, Lead Product Marketing Manager here at ANSYS and I'm really excited about what we can do in fluids in ANSYS R 18. Hold tight because you're going to hear some exciting stuff today.

In today's webinar, I'll go through some highlights and we'll talk about new packaging that will impact everyone who uses fluids. We'll discuss harmonic analysis, overset mesh, some integration with AIM and simulation apps, and advances in meshing, Fluent, CFX, and more.

After the webinar, visit [www.flex.com](http://www.flex.com) for more details about specific advances in these products. You can also go to the customer portal on ansys.com for update presentations and a whole page on the fluids release highlights with cool videos.

I'm excited to talk about the new fluids packaging and our revamped product line for fluids. We want to provide the best possible CFD capabilities in simple packages for everyone.

The new lineup includes: 1. ANSYS Fluent, our entry point for the product line, designed for various physics applications, including CFD, structures, electrical, and magnetics. 2. ANSYS CFD Premium, for experienced engineers and people who want the best validated CFD results across a wide variety of applications.

This package includes both CFX and Fluent. 3. ANSYS CFD Enterprise, for large or sophisticated users who need all the tools for their organization. This includes everything in CFD Premium, plus ANSYS AIM and additional productivity tools.

Each package is also available in solver-only packages or solver-only bundles. Additionally, you can buy the ANSYS CFD PrepPost package for multiple prep posts while your simulation is running.

We've amped up our high-performance computing pack, with the first pack now starting out with ten cores for structures or fluids packages.

ANSYS Fluent, CFX, and Polyflow still deliver the same great performance, with everything operating just like in release 17, but under the ANSYS R18 license manager. For those using our multi-physics bundles, the ANSYS Mechanical CFD or the ANSYS Mechanical Maxwell CFD bundles have not changed yet.

We are evaluating changing those and will provide updates later in the year. If you're an ANSYS CFD user, you can migrate to the ANSYS CFD Premium Package or the ANSYS CFD Enterprise Package at no additional charge.

Contact your ANSYS account manager for any questions about cost, migration paths, or impact on other products. Let's dive into breakthrough harmonic analysis for turbo machinery simulations.

ANSYS has been working on this problem for many years, and we've rolled out tools to speed transient blade row simulations. Harmonic analysis allows you to solve these blade row problems in the frequency domain, minimizing hardware requirements and time spent.

In ANSYS R18, we're focusing on the blade flutter problem, with plans to expand this technique beyond that in the future. We've also enhanced and expanded our offerings in overset mesh.

This technique allows you to have a separate mesh for each of the moving items, plus a background mesh, optimized for each product or object. The solver connects these cells, making it easy to account for motion in your simulation.

In ANSYS R18, we've done a cool storage separation simulation using overset mesh, and we've improved the density-based solver in Fluent for compressible flows. Overset mesh can simplify simulations where you have structured mesh around individual parts, making it valuable for various applications.

For those less experienced with CFD, we've bridged the gap between ANSYS AIM and ANSYS Fluent by allowing you to use the simple model simplification and meshing tools in ANSYS AIM to prep models for ANSYS Fluent.

This enables you to take advantage of Fluent's depth of combustion research and complex physics models. Simulation apps are another area I'm excited about. These apps can improve workflows, speed results, and build best practices for your simulations.

ANSYS has an app store with hundreds of apps, many of which apply to fluids. These apps are created by ANSYS developers, support teams, universities, consultants, and channel partners, allowing you to benefit from the expertise of our ecosystem.

Let's discuss some specific updates and details for certain products. For meshing, ANSYS R18 makes it easier than ever to get great results using CFX and Fluent by speeding and simplifying your meshing and model preparations.

We've been able to reduce meshing times for complex geometries by 40-80% over the last few releases. In ANSYS Fluent Meshing, we've made enhancements across the board, including hexa core three times faster, stitching up to ten times faster, and tech meshing through 10-30% faster.

These improvements will make a significant impact for smaller models and an especially big impact for those doing large models that take significant periods of time. We've also improved ANSYS Fluent with a better user experience, focusing on robustness, speed, and setup times.

The HDF compression reduces file size, and new models like the quarry model accurately simulate water oil displacement in oil and gas applications.

For ANSYS CFX, we now support flank milled blades directly in blade modeler, account for movement in the hub or shroud, and monitor live output as you're running in CFX post.

In ANSYS Poly Flow, we've added capabilities for thermal forming of non-isotropic material, poly flow extrusion of ANSYS AIM, and conjugate heat transfer for the adjoint solver. Thank you for joining me today.
