ANSYS Workbench was designed to be a parametric and persistent platform so that you could easily perform design studies and really get into simulation driven product development. Tools like DX can help you drive those parameters, but first, you need to parameterize your model.
You can parameterize the physics or even the meshing, but being able to parameterize the CAD using our bi-directional CAD interfaces is a real ANSYS Advantage. Continue reading

Piezoelectric devices surround us in our everyday life. Our cars and trucks contain many piezoelectric devices, including fuel level sensors, air bag deployment sensors, parking sensors and piezoelectric generators in the wheels to power the tire pressure monitoring system. Your smartphones or tablet contains piezoelectric sensors that detect the motion and orientation of the device, which my kids were using to good effect to play “Need For Speed” yesterday. Many of us have ink jet printers at home, which can use piezoelectric printer heads to eject thousands of drops per second. Continue reading
Diffusion is the process by which subject is transported from one part of a system to another as a result of random molecular motions, which is analogues to transfer of heat by conduction. Examples of diffusion are, but not limited to, spreading of odors and smoke (in gas), dissolution of colored dye in water (in liquid), formation of alloys, solid-state reactions, formation of new grains in cold-worked metal, improving surface wear by carburizing, gas purification, impurity doping of silicon wafers for integrated circuits.

Have you ever wanted to break up a model in multiple different zones and then mesh each with the best method possible? What if that could be done automatically? And of course, all the zones should be mesh-conformal, and all the mesh should be high quality. That is what ANSYS multizone meshing is for. This post is to explain a bit more about how it works and I also included a rough little video about how to use it inside the ANSYS ICEM CFD meshing tool. Continue reading
Whether you are an experienced user or beginning with our tools, or even looking to know what ANSYS tools can do for you, you can benefit from great videos that are available on YouTube. I am amazed at the quality of some of these user-generated videos. Looking back at my playlist from last year, I can give you a short list to start with. Continue reading
In a previous blog, I discussed how the “5-box trick” can be used to visually represent the steps in an ANSYS nCode DesignLife fatigue simulation. In this blog I will discuss the “Load Mapping” box in more detail.
FE analyses provide stress/strain results at distinct times or frequencies, but fatigue damage is caused by fluctuating stresses/strains. To assess fatigue damage, various load mapping techniques are used to convert the FE results into stress/strain histories and calculate the stress/strain ranges produced by those histories.

When I first got introduced to composites as a student (many years ago!), I remember having felt amazed at how powerful yet complex materials they are. In a recent interview published in Composites in Manufacturing, my colleague Marc Wintermantel expressed the challenge of designing composites products very nicely: “When a designer uses simulation software to define composite part points in space they have a tremendous amount of additional design options and parameters to deal with.[…] These options are so large that you need to depend on optimized simulation tools because the computations go way beyond most people’s abilities to perform these tasks by hand”. And indeed, how can an engineer figure out what the optimum stackup is for a given applications with so many possibilities for fabrics thicknesses, orientations or location choices? Steel or aluminum are much easier to deal with! Continue reading
