Many companies, large and small, have individuals or groups using powerful engineering simulation software like ANSYS Mechanical — one of our flagship products. These analysts tackle some of the most complex and challenging engineering problems for their organizations.
These same companies often also have separate teams of engineers working daily on new and evolving product designs. They are often experts in CAD modeling, using CAD-embedded simulation tools to evaluate their designs. These basic simulation tools provide some useful guidance, but often fail to provide the accurate results needed to refine and optimize designs with confidence. Consequently, many design simulations must be handed off to the relatively small number of simulation analysts using trusted simulation tools like ANSYS Mechanical. Continue reading
Do you wish you had a way to build and test your ideas virtually before investing in physical prototypes? An easy, accurate method that accelerates design timelines and reduces costs?
We all have ideas. Product designers strive to come up with ideas for innovative products. In the modern era, most products are not simple and must fulfill multiple functions in addition to being cost-effective and stylish. A good idea for a product often means understanding how a thousand smaller ideas work together to create the whole. Unfortunately, it is expensive to physically test every idea or many versions of the best one. Fortunately, upfront simulation helps engineers optimize their product idea before building the first physical prototype. Attend our webinar to see how. Continue reading
ANSYS AIM brings easy simulation to every engineer. The results from these simulations can be used to create fantastic images that bring your simulation to life.
You may have noticed a new graphics display mode that can be enabled by clicking on one of the toolbar buttons in ANSYS AIM 17.0. Its name is Enhanced display, and it is the third display mode option after Standard and Translucent displays: Continue reading
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).
Ease of use with guided templates Continue reading
For the past few weeks, the ANSYS blog has published many posts and ANSYS has held a number of webinars describing the advantages that ANSYS 17.0 provides for turbomachinery simulation. In the following, I will review these events and provide my summary of 10 (out of many more) exciting developments:
- A focus on HPC delivers significant speedups and ability to handle larger models, for both CFD and mechanical simulation.
- A new mechanical model simulates journal bearings, additionally providing important inputs of stiffness and damping for rotordynamics simulation.
- Fracture analysis is faster and easier with arbitrary crack surface definition and post-processing.
Preparing students for the real world means introducing them to industry-standard tools such as ANSYS AIM — as early as sophomore year.
Undergraduate engineering students are incredibly busy, overloaded with curricular activities. My mechanical and mechatronics engineering students carry a load of five courses in such complex subjects as mathematics, physics, materials, thermal science, and automation and control. Every four months, they also complete a co-operative education term in industry.
Because undergrads are so busy, I was shocked two years ago when a group of second-year students approached me about incorporating a new project into an already-challenging class, numerical methods. Continue reading
Engineering simulation software use among all types of engineers is growing rapidly. We already see our most innovative customers rapidly deploying simulation design software to engineers at all levels in their organizations. Gone are the days when a single engineer could design the whole product, or when a company could afford to develop and sell non-optimized products, such as bike frames that are strong but also heavy. Product development trends towards faster, better and cheaper mean that trade-offs have to be made between different goals to optimize the overall product, such as creating a bike that is strong and lightweight. Simulation helps companies get products to market faster while balancing their objectives. Easier engineering simulation software for every engineer is the solution. 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.

In my almost 20 years of work at CADFEM, an Elite channel partner of ANSYS in central Europe, I have seen a continuous transition in the usage of simulation from experts to development engineers. One big step in this direction was the introduction of ANSYS Workbench. A second — often undervalued — approach, how simulation helps our customers in a better product development is the usage of automated simulation processes by implementing products such as ANSYS AIM.

In all real life flows, the properties of a fluid material vary with pressure and temperature. The degrees of these variations depend on both the fluid itself and the flow regime. Some engineering simulations can assume constant material properties, but compressible effects are considered significant above a Mach number of around 0.3. Hence, in order to model applications such as external gas flows, nozzles and exhaust systems, material modelling techniques are required that can capture these material property variations.
In ANSYS AIM 16.2, we have incorporated the ideal gas model to determine the fluid density using the ideal gas equation of state. AIM also provides users a way to prescribe temperature dependent variations of other material properties (Specific Heat, Dynamic Viscosity and Thermal Conductivity), either by using an algebraic expression or by defining a table of values.
