3-D Design Helps Pool Cleaning, Accessibility Go Swimmingly

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

Dragonfly: The Mysterious Insect Driving Engineering Innovation

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

Multiphysics Simulation of a Car Side Mirror with ANSYS AIM

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

Submodeling: Simple Solutions for Large-Scale Problems

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.

Importing ECAD Trace Data for Better Thermal and Vibrational Analysis

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

Billet Designs Uses ANSYS SpaceClaim as Primary 3-D CAD Tool

Billet Designs is a small engineering firm that found great success in using ANSYS SpaceClaim as their primary 3-D CAD tool.

His broad background in various industries gives him a unique and expansive knowledge into common design and product development issues and challenges. As the owner of a small engineering firm, he has to balance product design with marketing, order fulfillment, sales, manufacturing and general development of his product line. Continue reading

Concept to Optimization with Upfront Simulation

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

Forward Thinking in Reverse Engineering

What is reverse engineering and why do I need it?

Reverse engineering has been an industry buzzword for some time and it has come to mean several things. The traditional picture it conjures is of several engineers gathered around a physical part, taking various physical measurements in an attempt to fully understand its shape and form. Their end goal is to re-create the part through any one of several manufacturing methods, where the manufactured part is nearly identical to the original.

Easy Simulation for Fatigue Analysis in ANSYS AIM

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).
