Many of you are using CAD tools like Creo Parametric along with ANSYS Workbench, but some of you are not using them parametrically. Of that group, there are probably a few who just really enjoy irony (and probably typewriters and rotary dial phones). However, others have been asking about how to link these tools together, or how to define parameters in Creo, or how to build robust parametric models, or how to parameterize settings in Workbench, or how to create tables of design points. These things are not hard to do, so I put together a video to illustrate. Continue reading
Recently, several members of the ANSYS DesignXplorer development team were invited to attend a conference in Paris on robust and reliable design. It was organized by IFMA (French Institute of the Advanced Mechanics), PHIMECA Engineering and NAFEMS. The purpose of the conference was to exchange experiences, problems, approaches and solution methods between industrial and academic people in the domain of uncertainties, reliability and robustness.

- Contact(Underlying Element)
- Contact (Contact Element)
- Target (Underlying Element)
When you choose ‘Contact(Underlying Element)’, the code is selecting the contact elements associated with that region, selecting nodes attached to the selected contact, and then selecting elements attached to the selected nodes before calculating the reaction.
Below is an equivalent APDL command script, where “cid1″ is a parameterized contact element type number for the region of interest. Continue reading
Sometime ago, I wrote an article entitled Best of Both Worlds: Combining APDL with ANSYS Workbench for Structural Simulations. When I read this article today, I think of three things:
- We have made a lot of progress in our latest releases so the use of MAPDL is reduced or irrelevant for the most common tasks we perform. With our added options, loads, or boundary conditions, models can easily be accessed by everyone without commands.
- The content of the paper is still relevant, as many of you have created and validated APDL scripts over the years that you can reuse “as is” in the Mechanical application.
- And last but not least, you can now give all of your scripts a Workbench flavor by integrating them in the Mechanical application through buttons, menus and new items in the simulation tree.
The 2011 earthquake and Tsunami in Japan led to severe loss of many structures and equipment. Can engineering simulations make us better prepared for such natural calamities?
Most organizations analyze the different components with great details for various failure conditions. But, seldom do they do a complete system analysis due to enormous computational requirements. With robust system level design the complex/large equipment could have survived the earthquake better.
Even with ever increasing computational power, solving larger FE models remains a challenge. Analyzing the complete system, like vibration analysis of a full-vehicle or full data-center-rack remains out of scope due to their enormous model sizes. At ANSYS, we focus at all levels of engineering analyses and help our customers achieve robust system level design. Continue reading
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?
