Overcoming Convergence Difficulties in ANSYS Workbench Mechanical, Part I: Using Newton-Raphson Residual Information

Unable to converge.  Convergence Failure.  Failure to Converge.  Never nice words to see when you are trying to get your simulation done.  If you’ve encountered convergence failures while running nonlinear structural analyses in ANSYS Workbench Mechanical, this two part series is for you.  What is a convergence failure?  In a nutshell it means that there […]

Suppressing New-Line Characters in APDL, and a Better WRTTBL.mac

OK, it is Friday afternoon and if I do not write something soon the week will be missed. We did not do a seminar this week so I can not just post the notes and some comments from the webinar, bummer.  All of the real tech support people at PADT have been busy with training, […]

Other Stuff Every User Should Know about Tables in ANSYS Mechanical APDL: Nesting and 4 or 5 Dimension Tables

About a month ago we published an article on “What Every User Should Know About Tables in ANSYS Mechanical APDL”  At the end of that article we had a section on “Other Stuff”  and expressed our hope to cover those subjects in the future. The future is now.  If you are not very familiar with […]

PADT will offer VCollab along with VCollab’s facilitating CAX file format to deliver on the growing need for smaller simulation result files and increased efficiency in data transfer to its customers in […]

Composite Sketching, ANSYS Style: Copying a Sketch from One DesignModeler Session to Another

Recently a customer approached me and told me that he had a sketch in one DesignModeler database that needed to be copied over to another DesignModeler database and asked me if it would be possible to do so. My initial reaction was, “No way, dude be trippin’,” because that’s how I talk in professional settings. […]

ANSYS 14.0 Service Pack Summary

You may have noticed there are several official service packs available for ANSYS 14.0. In case it’s not clear to you what each of these service packs is for, here is a brief explanation to hopefully allow you to determine which of them you may need for your particular application of ANSYS products. ANSYS140.0.1: Service […]

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 […]
