Combining APDL with ANSYS Workbench for Structural Simulations

best of both worldsSometime 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:

  1. 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.
  2. 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.
  3. 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.

ANSYS Webinars, Seminars and Events This Week

Learn ImageWe 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!

Engineering the Products We Use

Things we use every day — like this Herman Miller desk chair — are designed using engineering simulation

Sometimes, things are far from what they seem at face value. Years ago, back when I was a TV producer, I was especially drawn to editing. It was a tedious process (at times, it could take one hour of work to create just 60 seconds of a program), but the excitement that came from seeing my idea take shape on the small screen was far more valuable than all the caffeine in the world. The upshot was that whenever I went to see a movie on the big screen, I paid more attention to how the film was edited instead of the plot, the actors, the videography, the music, the overall experience … Years later, during the most recent leg of my career track, I discovered how engineering is important to successful product development  — and a similar thing happened.

ANSYS Webinars, Seminars and Events This Week – Sept. 17

image of Learning text on a keyboard ANSYS Webinars and EventsAnother full week on the horizon for ANSYS webinars, seminars and other events. Starting today, Sept. 17th, you can visit with our representatives at the  IEEE Energy Conversion Congress and Exposition in Booth #202 in Raleigh, North Carolina. If you’re in Germany, ANSYS is at the Husum Wind Energy trade fair for the international wind energy industry Sept. 18-22. In Paris, France, we have a full-day seminar focused on numerical simulation and facing the challenges of the offshore wind and tidal markets. Admission is free for this event, however, registration is required.

Here’s the full calendar for this week. Register for the event of your choice today! Continue reading

The Challenge of Point Cloud Data Mapping for Structural Engineers

Many structural engineers face the challenge of mapping (interpolating) data — such as pressures, thicknesses or temperatures —  on a finite element mesh (also known as point cloud data mapping). This often happens within companies where the analysts performing CFD or thermal analyses are not the ones performing the structural analyses. This also happens when the company is using tools from different providers.

Common data that analysts need to import as boundary conditions are pressures and temperatures. For example, think of a gas turbine where pressure and temperature results  from the CFD computations need to be used for the structural analysis.

How Do I Get My Nonlinear Contact Model to Converge?

There are almost as many answers to this question as there are applications for nonlinear contact. In conversations that start with this question, my first response is often “Well, … it depends”. That answer might sound like a vague side step, but truthfully speaking, the answer to solving a nonlinear contact problem really does depend on a number of factors that can vary in importance from one model to the next. In your ANSYS structural mechanics software, you’ll find a rich library of tools in the form of contact element key options and real constants, as well as solution control options, to help you calibrate the program to fit the specific demands of the contact application.

Don’t Be Afraid of Nonlinearities

Are you dealing with assemblies? Then you need some sort of contact modeling. Are you designing products with plastic or rubber parts? You need an appropriate nonlinear material model. Are you dealing with large deformations? You need to include the effects of geometric nonlinearities.

Should I Do A Response Spectrum Analysis — Part I

If you do technical support long enough you will discover there are only ten questions. Of course there are a myriad of small difficulties, irritations, limitations and complaints that customers call in about, but I’m not talking about those. I’m referring to questions which are almost philosophical in nature.  In my area of linear dynamics, one of the ten is, “Should I do a response spectrum analysis?”
