ANSYS ICEM CFD Multizone

mz_submapper_aniHave 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

How to Use Creo Parametric Parametrically with ANSYS Workbench

Creo WorkbenchMany 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

Workbench CAD Readers for ANSYS ICEM CFD Meshing

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.

ANSYS ICEM CFD import

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

ACT Templates for ANSYS DesignXplorer

Application Customization Templates - ACT

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

ANSYS Advantage for Simulation Driven Product Development

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.

DXWordsFor 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

“Bring Your Child to Work Day” at ANSYS

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

New HPC Parametric Packs in ANSYS 14.5 – Tutorial

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

ANSYS ICEM CFD Interactive

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.
