ANSYS CFX Solver Manager Instructions for Linux

Since PADT has been building the CUBE machines (, we have developed a need for clear-cut instructions for running parallel benchmarks with ANSYS software tools on the CUBE machines (which come standard with the CentOS Linux 64-bit operating system).  The computational fluid dynamics (CFD) solver ANSYS CFX is one such tool.  I have summarized instructions […]

Workbench and Excel, Part 2: Driving Workbench From Excel with Python

For a couple of releases now you have been able to use the very common scripting language python to script applications that are considered Workbench native: the project page, Engineering Data, DesignXplorer, and the Parameter Manager.  This is pretty cool and something that we will cover in a future The Focus article.  But one thing […]

Dust In the Wind: Stress and Strain Results in Workbench Mechanical vs. Mechanical APDL

Twice in the last week we’ve taken tech support calls in which the users questioned why their stress or strain results were being reported differently in Workbench Mechanical vs. the results from the same results file in /POST1 with ANSYS Mechanical APDL.  After answering those questions it was pretty obvious that a Focus blog entry […]

Using User Defined Results in ANSYS Mechanical

I first started contemplating this article several weeks ago, and I was planning on somehow working in a Jersey Shore reference.  But now that I’ve relocated to Colorado and am recovering from a climbing trip that was a bit above my ability, my creative juices are a little low (they were used up trying to […]

Parallel Performance: ANSYS FLUENT R13 with Service Pack 2

Recently, PADT has conducted some parallel benchmarks with our Linux cluster.  The model used for the tests is an ANSYS FLUENT *.cas file with 26.5 million cells and 6.5 million nodes.  The physics in this model are fairly simple; it is modeling external, steady airflow over an object.  Simulations of 10 iterations were conducted using […]

Retrieving Accurate PSD Reaction Forces in ANSYS Mechanical

We just finished up a tech support call for a customer that wanted a way to get accurate reaction loads from a PSD run in ANSYS Mechanical. Alex Grishin took the call and provided a nice example to the customer, so we thought we would leverage that and share it with all of you.  Even […]

How to Get a Cool Grip on Your Data Center Cooling in Three Easy Steps!

Over the years I have learned to do more with less. When it comes to information systems world, you all know the equation is often much more with much less. One of my to-do’s over the years, umm that continued to get bumped down on the priorities list. It is the juggling act of making […]

Workbench and Excel, Part 1: Using the Excel Component System

It is a fact.  Microsoft Excel is the most used engineer tool in the world.  If you are like me, you do everything you can’t do in ANSYS in Excel.  And a lot of the time you wish you could talk directly from Excel to ANSYS – and in the day many of us wrote […]

How To run ANSYS Release 13.0 Workbench on 64-bit Linux

Getting ANSYS Workbench up and running on Linux at R13 is pretty simple.  You just have to make sure that a few things are in place and some packages are loaded.  Then it works great.  Here is a quick HOW-TO on getting things going: Pre-Install Tasks Install CentOS 5.3 or greater or RHEL5 Download and […]

Dad, What Do You Do at Work?

I’m sure the question comes up for a lot of us from time to time, whether from one of our own offspring, another relative, or an acquaintance.  “Just what is it that you do, anyway?”  Typical answers might be something short and sweet, such as, “I’m an engineer.”  A more detailed response might be, “I […]

Knowing the ID of Coordinate Systems Created in ANSYS Mechanical – or perhaps – You didn’t know that, everyone knows that…

During this weeks webinar on Using APDL Snippets in ANSYS Mechanical a question came up about coordinate systems. I actually don’t remember the original question, but in answering it the question came into my mind: how do you get access to the ID of coordinate systems that you create in ANSYS Mechanical? For a lot […]

Files and Info from “Using APDL Snippets in ANSYS Mechanical”

We just finished the webinar “Using APDL Snippets in ANSYS Mechanical” and wanted to share the files we used and some additional information.  The presentation can be found here. The sample script for plotting mode shapes is here. You can view a recording of the presentation here on our WebEx site. PADT’s ANSYS Webinar Series […]

A Further Assessment of Design Assessment

Last weeks PADT ANSYS Webinar Series webinar was on a little used feature in ANSYS Mechanical called Design Assessment, or DA.  If you missed it, you can view a recording at: And a PDF of the presentation can be found here: As promised, this weeks The Focus posting will be a follow up on […]
