ANSYS Mechanical Scripting: HOWTO Part 4

Where we left Off Last Time… In the third part of this series, I left you with an introduction to the ANSYS Selection Manager and Geometry B-Rep.  We also created a sample script that iterated over all of the faces in a selected body and created a named selection for each face.   We built on […]

IT Tips – Is SP1 for Windows 7 Going to Slow Down my Machine?

ANSYS R13 Lemans CPU Wall Clock Benchmark Results Before and After a Windows 7 64-bit SP1 Update I was curious what sort of impact the Windows 7 SP1 upgrade would have on a new install of ANSYS R13. Would the Service Pack upgrade have a positive or negative impact on the ANSYS R13 and additionally […]

FE Modeler Part 3: Morphing Meshes

In the first two parts of this series we talked about how to use FE Modeler to translate meshes and how to create geometry from meshes.  The third “big” thing that this tool does is allow you to morph a mesh to a new shape.  There are a few less important things that FE Modeler […]

Mapped Face Meshing in ANSYS Workbench

In the era of automatic tetrahedral meshing, many have lost their way.  Wondering analysts simply read in their geometry, specify a few sizing controls, hit a mesh button and get a mesh.  But in the end, they receive a mesh that is not ideal, especially on the surface.  What these meandering meshers need is a […]

Mid-side nodes: Do they really help?

Do those pesky mid-side nodes really do anything other than increase my node count and runtime?  Over the years, I have heard that question over and over. “Do I really need them?”  If you are using tetra elements, then the answer is absolutely, “Yes!”  They even do more than just give you nice curvature to […]

Using the Solar Load Model in Fluent

One of the useful features in ANSYS Fluent is the solar load model. This capability can be used to calculate the effective radiation load based on the position on the earth’s surface (latitude and longitude), the model orientation with respect to North, the time of day, the season, and established conditions for clear or cloudy […]

FE Modeler Part 2: Converting a Mesh to Geometry

One of the “Holy Grails” of simulation is the ability to take a Finite Element mesh and convert it into geometry that you can then use to create a new mesh or import it into a CAD system as CAD geometry.  What most users do not know is that ANSYS, Inc. has a product that […]

Direct Modeling with SpaceClaim

Those keeping up with ANSYS, Inc. update presentations may have seen mention of a new product called ANSYS SpaceClaim Direct Modeler.  ANSYS SpaceClaim Direct Modeler is a  slightly modified version of the CAD package SpaceClaim (from the SpaceClaim Corporation).  It is sold by ANSYS, Inc. and can operate either as a stand-alone application or integrated […]

Caps and Limits on Hardware Resources in Microsoft Windows

Sometime around 3am last October I found myself beating my head up against a server rack. I was frustrated with trying to figure out what was limiting my server hardware. I was aware of a couple limits that Microsoft had placed into its OS software. However, I had no idea how far reaching the limits […]

AMD Opteron Magny-Cours Processor Wins InfoWorld Best CPU (Parallel Processing)

It was nice to see that the chip PADT has been using to build very inexpensive compute clusters just got recognition from an industry leading magazine: Read the InfoWorld article here. When we talk about these systems some folks look at us like we are a bit insane, “AMD can’t be a better solution than […]

ANSYS CFX: Going 2D in CFX

If you have had the chance to work with CFX, most likely you have been working only with three-dimensional models. You usually receive a CAD model or create your own geometry and then use one of the many meshing tools available in ANSYS to mesh your 3D geometry. However, what if you are tasked to […]

IT Tips: Setting Up FreeNX for Remote Access to Linux Machines from Windows

How To Install FreeNX with Key-based authentication on CentOS 5.5 in a Windows Platform Environment   In this article I will show you how to install and configured one of our more popular remote access programs here at PADT, Inc.  The software that I will be showing you how to install is called FreeNX.  FreeNX […]

New Year, New Articles, And New Features on The Focus Blog

Sorry about the multiple posts of the customization articles.  We are still figuring out the most efficient way to post things to this blog.  LiveWriter seems the best, but we have trouble editing a post or publishing with formating.  Still learning. We also upgraded to BlogEngine V2.0.  Things seem more stable and a bit faster. […]

ANSYS Mechanical Scripting: HOWTO Part 3

Where We Left Off Last Time… In the second part of this series I left you with a recipe for discovering ANSYS Mechanical functionality by using entities in the GUI itself to help guide your search through the ANSYS source code that is shipped with every ANSYS Mechanical installation.  This technique is the first tool […]

An ANSYS Mechanical Scripting Example

Creating Unique Named Selections for Every Face in A Body. I’ve put together a simple example of creating a unique named selection for each face associated with a selected set of bodies.  This example demonstrates the some of the techniques described in Part 3 of this series.  I recommend you read that post first to […]
