This year, my two sons David (8) and Michael (7) had the day off school on the same day as our “Bring Your Child to Work Day” at ANSYS so I brought them in to the Ann Arbor office for the morning. As it turned out, I was the only one to bring in any kids that day — although there were organized events at the larger offices — so I decided I would just let them play with our software in the training room.
Neither boy had used SpaceClaim or ANSYS Mechanical before so I started by giving them some step-by-step guidance, but I rarely touched the mouse after the first 5 minutes. They each used their imagination and made multiple models. David’s first model started looking like a top hat, so he tried to make something reasonably reminiscent of the head of Uncle Sam.
His second model was more of an abstract solid that used a lot of push/pull fillets, which are easy to create and adjust in SpaceClaim. It looked very interesting under load. He was creating the fillets one at a time at first, but then really got going when I showed him how to hold down CTRL for multiple edge select. Continue reading →
What happens when a bird runs into a plane while the plane is soaring through the air? How do you identify exactly what happened in that split second? And since every action has a reaction, how do you determine if the plane is designed to survive a bird strike? Understanding the physics of split-second events: This is the arena of explicit dynamics analysis.
Now consider split-second impacts in golf. United States Golf Association specifications regulate the speed limit with which a golf ball leaves the face of a driver. Using a standard of approximately 109 mph clubhead speed, approved golf balls leave the face of the driver at about 180 mph on average. If you’re charged with designing balls and clubs, how do you get to the optimal design that meets specs?
We have seven ANSYS webinars for you to take advantage of this week where you can further your skills in your ANSYS software. Begin the week by gaining insight into the ANSYS Fluent Adjoint Solver, a groundbreaking new technology that ANSYS fluids customers are already beginning to take advantage of to help them improve their products quicker. Explore ANSYS Workbench, which provides a number of standard tools for structural mechanics simulations, or Ask The Expert about tips & tricks for modeling reacting flows.
And, if you’re on the road this week at DesignCon in Santa Clara, CA, stop by Booth 513 and say hello!
What works for manufacturing companies also applies to engineering simulation software providers. In a competitive climate, we all must aim continually for innovation, listen to the voice of our customers, anticipate swiftly changing needs, identify buyer expectations and make appropriate changes. I strongly believe that the parametric licensing and capabilities newly introduced with ANSYS 14.5 are truly innovative, standing out from the rest. They could become a paradigm shift in CAE, as they will make extensive design exploration and robust design a reality.
Given the market forces for increased product performance and integrity, engineering simulation undoubtedly can help manufacturers to evaluate more design ideas and reach the “best” design, one that works across a range of operating conditions. For that matter, many engineering simulation software providers today do offer design exploration and optimization tools. But despite the need, the adoption of these tools is relatively small. Our product manager for ANSYS DesignXplorer, Simon Pereira, regularly investigates the obstacles to further adoption, and, in each of his reports, the biggest hurdles appear to be unacceptable turnaround times, shortcomings in usability and lack of available licenses.

ICEM CFD interactive/batch controls can be found in the advanced options of several different methods in ANSYS Meshing.
ANSYS Meshing is the general purpose meshing tool found in the ANSYS Workbench environment. It includes a lot of powerful ICEM and TGrid meshing technology, but exposed in a simplified and automated way. For instance, MultiZone in ANSYS Meshing is based on ICEM CFD hexa technology, but without the learning curve associated with blocking, edge distributions, etc.
However, there are some occasions when advanced users want to take more direct and interactive control over their meshing. ANSYS Meshing allows advanced users to “pop the hood” on some mesh methods with the “ICEM CFD Interactive” options (TGrid interactive is also available as a Beta option). ICEM CFD interactive allows users to launch ICEM CFD with all its controls. You can do full hexa blocking, tetra/prism, shell meshing, diagnostics, automatic or interactive mesh editing, etc. You can start from just the geometry, transferred to ICEM CFD with meshing parameters, or you can actually start with the mesh and adjust it from there. For instance, you could generate an PI tetra mesh in ANSYS Meshing using “Interactive” with “Post Operation” and then use the extended ICEM CFD tools to replace the mesh with a smooth delaunay fill or 12 Tetra to 1 Hexa conversion, smooth, and then return to ANSYS Meshing.

This week our one-hour ANSYS webinars include the Ask the Expert series, Power Electronics for Hybrid & Electric Vehicles and Learn How Mesh Morphing Accelerates CFD-Driven Shape Modifications. You can find a full description of each of these, along with dates, times and a link to register below. Participation is complimentary.
As the month of April winds down, you might like to get a jump on planning your calendar for May. In our Automotive Series, we have two great topics in the line-up. On May 8th & 10th, Dr. Evangelos Koutsavdis will be discussing why aerodynamic noise generation is becoming a very important aspect of product quality. You’ll be able to join in on the discussion where a panel of experts will be available to answer your questions.

With the release of ANSYS 14.0, ANSYS Fluent users can perform two-way fluid–structure interaction (FSI) simulations using the ANSYS next-generation coupling technology — system coupling.
The system coupling component in ANSYS Workbench offers a generic way to couple two or more participants in the Workbench environment. In release 14.0, you can link Fluent and ANSYS Mechanical via system coupling to facilitate FSI simulations.
This post provides a broad overview of the capabilities offered with system coupling and the types of cases you can solve. I’ll try to avoid just listing the features. Continue reading →
