We occasionally get questions about writing if/else parameter expressions. For instance, users may be setting up a parametric model where the heat turns on only under certain conditions or perhaps an input or output is best expressed as a step function.
Yes, you can do this with expressions. Lets look at some basic examples. Continue reading
“Meshing”… Usually throwing this single word to a group of structural or CFD analysts will start interesting and passionate discussions. Meshing is definitely a key part of the simulation process and requires attention. As analysts, how many hours did we or do we spend on meshing? Probably too many — especially if you have been in the simulation world for many years and started when automation of meshing was not so common. But after all, meshing is just one of the tools that we need to get accurate results and we should spend more time looking at simulation results than meshing our models. Continue reading
In a previous post, I have presented how to apply a harmonic base excitation in ANSYS Mechanical 15.0 using three different techniques. Among those techniques, we had the great ACT extension that has received a great attention due to its ease of use and practicality.
ANSYS 16.0 offers the capability of applying a harmonic base excitation natively, and without the need for the ACT. Acceleration applied as a base excitation uses the Enforced Motion Method. Continue reading
In previous posts, we showed you how to parameterize DesignModeler, Spaceclaim and Creo Parametric. Very recently, we had for for creating Named Selections and Parameters in NX. Today, we finally get to one for Catia. I don’t have Catia installed on my computer, so thanks to Richard Mitchell, UK Sales Support Manager for recording the video.
Simulation driven product development has been a key theme at ANSYS for well over a decade, we often just refer to it by its acronym. It is the reason that ANSYS Workbench was designed to be a parametric and persistent platform. Tools like DX can help you drive those parameters, but first, you need to parameterize your model!

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
Are you a new user of ANSYS software interested in expanding your scope of expertise? Or are you an experienced user who wants to understand the best techniques to tackle a complex new application? Do you wish you had access to experts anytime of the day to provide you with short tips to get you on your way?
Well, we have some new content on the web just for you! 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
