When designing heavy equipment such as bucket loaders, truck bodies and diggers, finite element analysis tools, such as ANSYS, are a ‘must-have’ in any design engineer toolkit in order to assess the structural integrity of designs and ensure their durability and performance. But while FEA will provide engineers with a wide range of tools for setting up meshes, joints, and boundary conditions, there is one thing missing in this analysis: the bulk material itself that the machine is supposed to handle! DEM (Discreet Element Method) offers additional capabilities to account for bulk materials.
Developing a luxury electric vehicle (EV) from scratch with a short deadline demands organization and access to the right technology to get the job done. Lucid Motors of Menlo Park, California, met the first challenge by putting all the engineers in one room so the structural and aerodynamics engineers would know what the battery, motor and power electronics engineers were doing, right from the start. This collaborative environment has helped them to design a unique automobile with more passenger space by reshaping the battery stack, while optimizing the electric motor, the cooling system, the aerodynamics and the battery life.
Every numerical method relies on the accurate choice of models, solver settings, and material parameters in order to be able to mimic real-world behavior. This also applies to Discrete Elements Method (DEM) simulations. You could use standard material properties, but adjusting those material interaction parameters using automated calibration methods is a key step for accurate simulations.
You could use standard material properties, but if you want to simulate reality, it is important to understand that the materials actually vary from site to site. Adjusting those material interaction parameters using automated calibration methods is a key step for accurate simulations. Even with basic materials, friction and restitution coefficients between particles and particles and boundaries have to be adjusted in order to accurately predict the bulk flow behavior. When extra forces come into play, such as adhesion forces, those additional parameters also need to be selected and properly specified. Continue reading
As the founder and president of Wolf Star Technologies and the creator of True-Load software, which calculates the loads from measured strain occurring in moving vehicles, I would like to tell you a little about the struggles and triumphs I encountered (and overcame) in my engineering career and how this led to the creation of True-Load. This has culminated in the successful integration of True-Load into the ANSYS Workbench platform, so more engineers than ever will have access to my software and be able to integrate it with their ANSYS simulations.

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.

The ROV, or subsea remotely-operated vehicle, is frequently used in marine operations such as underwater mapping, pipeline inspection and surveillance, sending payload, maintenance and operations on subsea oil and gas equipment such as BOP (blowout preventer) and Christmas tree assembly, which controls the oil/gas/water flow out of the well.
Underwater environments create various challenges for the manufacturers of the vehicle robotics. In addition to structure integrity under high pressure, complex underwater hydrodynamics characteristics due to coupling of motions in 6 degrees of freedom needs to be considered. Continue reading
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
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
