While packing for an office move, I came across some old ANSYS News Magazines. The oldest I have is 1st Issue-1989 and it was mostly about the 4th International ANSYS conference in Pittsburgh.

How analysis has changed since then. There were "Large Model Benchmarks" with Version 4.2 with models up to 6,000 Elements! Also a comparison of a VAX11/780 to a few models of PC's (with the blazing 20MHz 80387 Processor).

I remember those days; I started off running ANSYS on various time
sharing services and as a batch service on an IBM mainframe in the late
1970s. Both were expensive and had long turn round times so we were
quite early adopters when ANSYS became available on a PC. I think the
first PC we used had a 286 processor and and an additional paged memory
card. It would run 2D analyses reasonably well. For a while I would
get the ANSYS UK agent technical support people ringing me up for help
with questions about running ANSYS on a PC.

As soon as 386 processors and the 80387 co-processor were available at a
reasonable price we upgraded and it was a major step forward. I was
able to build and run a fairly detailed non-linear model of a crane hook
(which ANSYS subsequently used as an image for several years). It took
about 10 days of continuous running to get the results but when we did
they were very satisfactory and at last we were able to make money out
of offering ANSYS analysis services.

"ANSYS conference in Pittsburgh"... I LOVED THESE. What do we get now??? Zoom calls, ugh.

I started using Ansys in 1998 and I attended an APDL training class for a couple days leading up to the conference... taught by John Swanson! He was a fabulous teacher and I remember laughing pretty hard at all his anecdotes. By this time I'm sure he was a very wealthy man and was teaching the class for the sheer joy of it.

I think that was the conference when my wife traveled with me. We were both in our mid-twenties with no responsibilities. I snuck her into all of the ballroom lunches as my "co-worker". She's from Korea, so we decided that if she got any difficult FEA questions then she would feign broken English and I would answer for her.

Good Times!

The first conference I attended was in 1985; I believe it was the second annual Ansys conference. I presented a paper showing results from a simulation where I had to use PREP6 to expand the load into Fourier series (Yes, there used to be a Prep6 in addition to Prep7). Then I attended every single Ansys conference after that and I was also in the same class that Dr. Swanson taught the APDL class in 1998; I knew that was a very special class; one for the memories even back then...

I first used ANSYS 4.x in the late 1980's on a VAX mini computer. I think it was the VAX11/780 that was referenced in the magazine. I remember training classes in Washington, PA (I think I remember the office being in a residential neighborhood?) and also an ANSYS reseller in the NE United States, maybe CAE Associates.

I remember those days; I started off running ANSYS on various time sharing services and as a batch service on an IBM mainframe in the late 1970s.

I started that way only with a CDC remote service. First really significant problem was a rectangular opening in a cylindrical shell subject to internal pressure. Hard coded elements and nodes and god alone knows how many check runs made--over night of course, with debugging from flatbed plots. Took about two weeks to finish the report, which was all composed and edited by hand. Turns out that non-uniform deformations rendered the opening impossible to seal, but unfortunately no one really believed the results—ANSYS was so revolutionary that no one figured that the results could beat 'engineering judgment.'

I tried a problem like it years later one hot summer evening including all the graphics and nice tidy results summaries running remotely with my first Mac using a TEK/DEC emulator. Line speed to get results summaries was glacial, but much faster than commuting. And it gave me time to fetch a lager and crack it open.
