Running an APDL Command Snippet for Every Load Step in ANSYS Mechanical

This week went by very fast, and I never got time to do the more advanced article on tables to follow up on last week’s article.  So I was going to give up till someone stopped by my office to ask a question and I thought my simple and clever answer would make a nice […]

What Every User Should Know About Tables in ANSYS Mechanical APDL

I was having a discussion with a user who is very experienced with a FEA tool other than ANSYS. He wanted to define some properties with respect to time and his rotational speed and wanted to know how hard it would be to write a custom routine in ANSYS to do that.  I immediately explained […]

An Ocean in the Desert: What is AQWA?

Maybe you’ve seen AQWA show up in the list of ANSYS products to be installed on your computer, or maybe you’ve seen it as a topic in the ANSYS Help System and you otherwise wondered about it.  Is it related to Aqua Man or perhaps Aqua Lung?  Not at all.  If you are not familiar […]

Node Interaction in Mechanical, Part 4: Scoping Results to Nodes

This article is the eagerly awaited fourth and final installment in my series on interacting with nodes in ANSYS Mechanical. To review, the previous three articles covered picking your nodes, creating named selections from nodes, and applying boundary conditions to nodes.  I know some of you were wondering why it took a while for this […]

Solution Information: Monitoring your Solves in ANSYS Mechanical

There is a folder with a big fat exclamation point on the top of the Solutions branch in ANSYS Mechanical. It is called “Solution Information.”  Most users click on it after their run is done and maybe look at the output from the ANSYS Mechanical APDL solve.  And it is very handy to check your […]

Surface Projection Based Contact Detection

The ANSYS Mechanical APDL solver has a lot of contact options.  KEYOPT(12) this and KEYOPT(4) that.  I’m sure we all read Chapter 3.9 of the Contact Technology Guide to understand and remind ourselves on all these options.  I know here at PADT we always do so on the third Tuesday of every month… OK, maybe […]

Node Interaction in Mechanical, Part 3: Nodal Boundary Conditions

This article is Part three in a four-part series about taking advantage of the new nodal interaction capabilities in Workbench 14.0. In Part 1 I discussed how to pick nodes and retrieve information about them. In Part 2 I covered various methods of creating nodal Named Selections. In this installment I’ll address the procedures for […]

Node Interaction in Mechanical, Part 2: Nodal Named Selections

This is the second entry in a thrilling saga about interacting with nodes in ANSYS Mechanical. In Part 1, I addressed the various methods for picking and querying nodes in a Mechanical model. In this entry, I discuss various methods for creating nodal Named Selections. Creating nodal Named Selections is a key step in executing […]

Webinar Files: Moisture Diffusion Modeling with ANSYS at R14 and Beyond

On May 24, 2012 Matt Sutton gave a well attended webinar on the new moisture diffusion modeling capabilities in ANSYS Mechanical APDL at R14. Although we didn’t get a successful recording for this one (Matt has been chastised and done his penance for forgetting to turn on the recording…) we do have a PDF of […]

Node Interaction in Mechanical, Part 1: Picking Your Nodes

In version 14.0 of ANSYS Mechanical, ANSYS has rolled out its first capabilities for interacting with the underlying finite element model in addition to the geometry. In this version, the user can select nodes, create named selections from nodes, apply loads and constraints to nodes, and scope results to nodes. And it is glorious. In […]

Coordinating Coordinate Systems in ANSYS Mechanical

Coordinate systems are one of those things that are fundamental to Finite Element Analysis, but that most of us do not think about a lot.  They are there, but some users never fiddle with them. And some users are constantly futzing around with them.  We thought it would be a good idea to do a […]

Writing Text files with *VWRITE

A very common need in the world of ANSYS FEA simulation is to write text to a text file from within Mechanical APDL. Sometimes you are running in MAPDL, sometimes you are using ANSYS Mechanical but you still need to write stuff out using APDL with a code snippet. The way most people do that […]

Turning on Beta Features in Workbench

It is a busy week and I’m in between meetings for about 30 minutes, just enough time for a very short Focus posting for the week.  So, I thought I would share something I had to remember for the first time in a long time: How to access beta features in ANSYS Workbench. First off […]

Webinar Information: Constraint Equation Primer

Here are the files from the webinar held on Friday, April 27, 2012: A Constraint Equation Primer: How to Tie Degrees of Freedom Together PowerPoint: PADT-Webinar-ConstraintEquations-2012_04_27.pdf Link to webinar recording: No models or anything on this one.

To GPU or Not, This is No Longer The Question…

Executive Summary Without losing you quickly due to fabulous marketing and product information. I thought it prudent if I get to the answer of my question as quickly as possible. What was the question? Should I invest in a companion processor and an ANSYS HPC Pack? Yes, now is the time. If your current workstation […]
