In a wide range of structural applications, fatigue is common failure mechanism due to cyclic loading. Constant amplitude fatigue analysis is most commonly used to make a simple and quick estimate of fatigue performance or durability in absence of full time history based loading. With the release of ANSYS 17.0, we are excited to introduce fatigue analysis in ANSYS AIM for constant amplitude loading with support for both high cycle(stress life) and low cycle fatigue(strain life).

On January 27, ANSYS released its biggest version ever, ANSYS 17.0. Although the ANSYS simulation platform is renowned for its comprehensive coverage of virtually every industry through its extensive range of simulation tools, this latest release is particularly suited for the healthcare industry, whether you are modeling structural, fluid or electromagnetic applications — not to mention those of you engaged with multiphysics modeling. Among the hundreds of new features coming with this release, it might be easy to miss those which are truly important for the medical device, pharmaceutical or clinical sectors. Let me highlight 3 new or enhanced capabilities. Continue reading
Fidelity and accuracy is critical in CFD simulation. After all, physical prototyping and testing can only be reduced and even replaced by CFD if one can expect accurate results. Up to now, high fidelity, high accuracy results came with a price. Complex geometries — the realistic, no holds barred type — required hours of manual effort to clean up the model and then prepare the mesh. Users were tempted to cut corners and take short cuts that sped up prep but took a toll on accuracy and fidelity. Unfortunately, there is no way of knowing just how those inaccuracies skewed the results, putting any recommendations in doubt. For example, if you don’t resolve a boundary layer correctly then any aerodynamic drag figures could be highly inaccurate. Continue reading
2015 was a fantastic year for the medical Internet of Things (Medical IoT), in silico clinical trials and personalized medicine. Many thought leaders and industry pioneers elaborated exciting visions. Leading regulatory authorities, such as the FDA, encouraged a number of innovative approaches, including the large-scale adoption of computer-based models to streamline the regulatory approval process.

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
