We occasionally get questions about writing if/else parameter expressions. For instance, users may be setting up a parametric model where the heat turns on only under certain conditions or perhaps an input or output is best expressed as a step function.
Yes, you can do this with expressions. Lets look at some basic examples. Continue reading
In previous posts, we showed you how to parameterize DesignModeler, Spaceclaim and Creo Parametric. Very recently, we had for for creating Named Selections and Parameters in NX. Today, we finally get to one for Catia. I don’t have Catia installed on my computer, so thanks to Richard Mitchell, UK Sales Support Manager for recording the video.
Simulation driven product development has been a key theme at ANSYS for well over a decade, we often just refer to it by its acronym. It is the reason that ANSYS Workbench was designed to be a parametric and persistent platform. Tools like DX can help you drive those parameters, but first, you need to parameterize your model!

ANSYS Workbench was designed to be a parametric and persistent platform so that you could easily perform design studies and really get into simulation driven product development. Tools like DX can help you drive those parameters, but first, you need to parameterize your model.
You can parameterize the physics or even the meshing, but being able to parameterize the CAD using our bi-directional CAD interfaces is a real ANSYS Advantage. Continue reading
Have you ever wanted to break up a model in multiple different zones and then mesh each with the best method possible? What if that could be done automatically? And of course, all the zones should be mesh-conformal, and all the mesh should be high quality. That is what ANSYS multizone meshing is for. This post is to explain a bit more about how it works and I also included a rough little video about how to use it inside the ANSYS ICEM CFD meshing tool. Continue reading
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
ANSYS ICEM CFD has been using the Workbench CAD readers for a few years now, and for those of you using ICEM CFD in Workbench, it is drag and drop simple. But many of our stand alone ANSYS ICEM CFD users are not really aware of this functionality, so here is a blog about it.
In previous versions, we had the Workbench readers under “File => Workbench Readers”. The Workbench readers really supersede the old ANSYS ICEM CFD readers. They are up-to-date, easy to use, and offer connections such as JT Open and SpaceClaim that ICEM CFD never supported on its own. Talking to users, we found that many thought the Workbench readers option would only work inside Workbench or if they installed Workbench. To make the option more obvious, we moved the Workbench readers to the top of the list and renamed it “Import Model.”
Why “Import Model” instead of “Import Geometry”? Because the Workbench readers also support mesh formats! You can even select a *.wbpj and get both the geometry and mesh. During the import process, you can filter to make it easier to find the files that you are looking for. For instance, you can switch it to SpaceClaim to filter for SpaceClaim documents. Select your particular file (some formats will show you a preview of it), and click Open. Continue reading
Are you familiar with ANSYS ACT (Application Customization Templates)? ACT allows all sorts of great customization. You could use ACT to encapsulate APDL scripts, add new loads and boundary conditions, create custom results, or even integrate third party tools. For instance, Vanderplaats R&D just integrated their topology optimization product into ANSYS Mechancial via ACT.
The ACT Toolkit requires a license to develop extensions, but not to use extensions created by others or provided in our ACT library. Continue reading
Have you picked up a copy of ANSYS Advantage Magazine lately? You can see the latest issue online and even subscribe to receive notifications of new editions. Every quarter, ANSYS Advantage Magazine includes stories about how engineers are using simulation tools to develop better products. A key trend is that more and more of us are using advanced design exploration and optimization tools to drive their simulation towards the most optimum and robust designs.
For Q3 of 2013, ANSYS Advantage dedicated the entire edition to shine a spotlight on robust design and optimization. You can read about how oil and gas companies like Technip are using ANSYS DesignXplorer to ensure against undersea oil leaks. There is also an article about how the electronics industry is using ANSYS DesignXplorer to help explore their design space and improve product performance. There is even a tech tip article (that I wrote ;^) to explain how to use the relatively new HPC Parametric Pack licensing to run simultaneous design points more cost-effectively. 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
Simultaneous solve of design points reduces the time required for a parametric study, and the new ANSYS HPC Parametric Packs make that process very affordable.
As the product manager for ANSYS DesignXplorer, I am always interested in software-related improvements that can help ANSYS customers get more parametric analysis done with less time. For over a decade, the vision of ANSYS has been Simulation-Driven Product Development, which we call SDPD. Our solver technology is world class on its own, but we want our customers to get even more out of simulation. Instead of just using it forensically to see what went wrong, we designed our tools so product R&D teams can use simulation to drive product development. Continue reading
