Digital exploration has never been more vital to long-term business success than it is today. The product design space is exploding, driven by increasingly smarter devices, advanced materials, and next-generation manufacturing technologies like 3-D printing and mass customization. At the same time sustainability and cost put pressure on identifying and eliminating unnecessary safety margins, while still ensuring long-term product strength and durability. Design engineers have an unprecedented opportunity to innovate and explore product designs, but also orders of magnitude more complexity to manage. Continue reading
A few days ago someone asked me if ANSYS flagship products are appropriate for the “average” engineer, and more particularly design engineers doing upfront simulation. I believe the better question to ask is which ANSYS products are geared toward design engineers, and why.
More often than not, design engineers are quite familiar with 3-D modeling tools, which are the starting point of simulations in the product development process. But given their focus on product design, manufacturability, documentation, etc., they typically do not have time or prior experience required to learn how to use a fully featured simulation tool like ANSYS Mechanical or CFD.

As digital electronic devices continue to shrink and put greater functionality within consumer and enterprise products, thermal management continues to grow as the bottle neck for defining next generation architectures. Significant challenges exist today because the heat being generated continues to rise while the thermal envelope remains constant for silicon devices.
While some switching power converters have moved to III-V semiconductor materials such as GaN, the overall system still contains many silicon semiconductor devices that must meet traditional thermal envelopes. The removal of this heat has become a critical aspect of the design process, often being a very significant driver of what can be delivered within an electronic product. Continue reading
Geometry scripting, macros and batch files are great ways to automate repetitive tasks or reduce a complicated workflow to a single mouse click. Although you may have never written or recorded your own script, there’s a good chance you’ve benefited from one created by someone else.
ANSYS SpaceClaim recently introduced a geometry scripting environment that further eases common geometry related tasks. More specifically, it’s a simple way to record or write a set of commands that will automate repetitive tasks or make complicated workflows easy. It also serves as a method of extending the user interface to make otherwise impossible geometry by expanding the different things you can do with geometry. From replaying recorded changes on imported models to parameterizing variables only thought possible in a feature-based system, scripting is a powerful ally in making smart, robust geometry.

What comes to mind when you think of public swimming pools? A refreshing escape from the summer heat? Children playing and swimming? Free-swimmers, divers, and water polo players jockeying for limited space? How 3-D design makes pools cleaner and more accessible for everyone? Hmm. I may need to explain that last one.
While many of us focus on the positive aspects, there are some of us who avoid public pools: non-swimmers, of course; people concerned about bacteria and other health issues; and people with reduced mobility (PMR) who find accessing public pools difficult to manage and unwelcoming.
Hexagone, a French company founded in 1987, has made its mission to serve these last two categories of recreationists, designing and equipping public pools with professional high-tech cleaning devices and creating solutions that increase PMR accessibility and safety. Continue reading
Who hasn’t dreamt of flying like a bird? From Leonardo da Vinci’s drawings of flying machines to Otto Lilienthal’s gliders, inventors have focused, quite logically, on human transport. We now take flying on airplanes for granted. But mechanical flight on a smaller, insect-level scale is less well-known. Micro-air vehicles (MAVs) have gained popularity in recent years due to wide range of small-scale applications in areas such as military, transportation, electronics, security systems, search and rescue missions, video recordings and many more. Successful prototypes depend upon valid, yet imaginative, designs as a starting point. Continue reading
One of the most important problems in the automotive industry is the general multiphysics simulation of coupled phenomena, where multiple — and sometimes conflicting — conditions need to be accounted for, all at the same time. One common application is the resistive heating of a car side mirror.
Designing the mechanism for keeping the mirror defrosted must also take into account the structural response of the mirror as the external environmental conditions, such as air pressure and cold temperature, cause physical stress and thermal deformation. The task is a base requirement of the automotive industry and requires a full multiphysics approach, which is still a challenge for common finite element method (FEM) simulation. In this post, we’ll show you how our engineers at SVS FEM used ANSYS AIM to model a side mirror and multiphysics analysis to solve some of its difficult design problems. Continue reading
If you’re an engineer who has dealt with large simulation models, you know there’s often a trade-off between accuracy and solution time. Submodeling is a technique you can use to reduce solution time without sacrificing accuracy of results.
A common strategy you can use to look at the overall behavior of an assembly or complex part of a large model is to simplify the model during preparation by removing small details, like fillets and holes. Simplifying models in this way can have a significant impact on run times. This simplification, while not excessively affecting overall model stiffness, may result in lower resolution of localized stresses. What you need, then, is a mechanism that allows you to “zoom in” on these details to examine behavior around specific areas.
Many of our customers are reaping the benefits of the trace import functionality in ANSYS Mechanical, which accounts for the effects of copper distribution on every layer of a printed circuit board (PCB) — or printed circuit board assembled (PBA) — for your thermal stress analysis, modal, shock and random vibration simulations. Just think — you can capture the accuracy necessary to confidently make engineering decisions in a fraction of the time you are currently spending on lumped parameter models. In this post, I’ll give you a brief overview and explanation of the process. Continue reading
