About John Graham

John is an experienced application/mechanical engineer with specialties in sales, marketing, design, 3D modeling, and product development. He received his B.S. degree in Mechanical Engineering from the University of Missouri-Columbia and has been with ANSYS for nearly 5 years as an Application Engineer specializing in SpaceClaim. Prior to his current role he worked as a design engineer on a variety of products such as electric motors, linear motion guides, and fiber optic transceiver modules. John's passions include content marketing, technical teaching/training, project/product management, programming, and video production work.

Ideal Upfront Simulation Tool for Design Engineers

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.

Solution Dependent Expressions for Fan Cooling Simulation with ANSYS AIM 18

In ANSYS AIM 18, design engineers have reason to be excited about increased functionality for fluids, structural, thermal and electromagnetics. While the foundational problem-solving functionality has existed since AIM 16, new functionality is being added in every release so AIM can better address niche applications. One such enhancement I’d like to bring to your attention is solution-dependent expressions for applications like fan cooling simulation. While this isn’t something I guarantee you’ll use in your everyday simulations, it is a powerful feature needed for certain calculations. Continue reading

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

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. They specialize in wide variety of offerings for their clients, including product design for automotive and consumer products, programming, automation, PLC controls and robotics.

Steven Aguirre of Billet Designs says their main focus is on the design of electromechanical components of consumer products. 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

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.

ANSYS SpaceClaim Creates Accurate Weld Surfaces 10X Faster

Analysts often find themselves in the business of defeaturing geometry to prepare solid models for structural simulation. Removing rounds, filling holes, eliminating small features; the list goes on. Before ANSYS SpaceClaim, those tasks were time consuming at best. Realistically they were tedious, difficult, and a necessary evil.

Those necessary features exist either because of design requirements or because they are closely tied to manufacturing procedures. Weld geometry is no exception to the latter. However, unlike drafted surfaces or some complex rounds, weld geometry is necessary for both manufacturing and analysis. In the case of structural analysis using shell elements, or midsurfaces, the question analysts are left with is how to model them accurately. Continue reading
