AI for writing APDL macros.
Just for grins, I thought I’d try to get ChatGPT to write a simple ANSYS macro for me. It failed miserabely. ☹
Me:
Write an ANSYS APDL macro to convert body force temperatures on all nodes from Fahrenheit to Celsius.
ChatGPT:
! Macro to convert body force temperatures on all nodes from Fahrenheit to Celsius
! Ask user to input the name of the load
*GET,load_name,UX,'Enter the name of the load: '
! Loop over all nodes
Ntot = NODE(0)
DO i = 1, Ntot
Nnum = NODE(i)
! Get the temperature in Fahrenheit for the current node
*GET, Ftemp, NODE, Nnum, TEMP, load_name
! Convert Fahrenheit to Celsius using the formula (F - 32) * 5/9
Ctemp = (Ftemp - 32) * 5/9
! Set the temperature in Celsius for the current node and load
*SET, NODE, Nnum, TEMP, Ctemp, load_name

I used it to write some MATLAB and ANSYS APDL codes. For MATLAB, he did
pretty well. But for APDL, oh, wow! It was stupid. I asked him to implement
Some creep law using USERCREEP subroutine. It completely failed to be even
close.

I watched a YouTube video yesterday (https://youtu.be/pspsSn_nGzo) about getting Chat GPT to write C++ code for a parallel algorithm using a GPU(!). For background, the guy in the video is a Microsoft Engineer who wrote a lot of the stuff you've used in the last 20 or 30 years.
His take was that you can guide Chat GPT to get what you want, but there is a technique to it, much like writing & debugging code. CGPT can remember and improve if you correct it in the same session ... "Now take the code and make sure the variable X is defined this time" ... "This time make sure the memory is allocated on the GPU not the CPU"
He eventually got sensible working code out of it. He suggested letting CGPT do the bulk of the writing, combined with applying your expert knowledge to guide an correct as needed. For Computer Science 101 it can produce good results first try, but more complex things need more massaging.
APDL probably has a much smaller training set than Matlab & C++ so that may be an issue too.
CGPT won't take our ANSYS jobs today or next year, but it will probably soon be useful as a force multiplier for our work. Even if it writes 80% of the code and I just have to tweak a bit of it, that's 80% less code I have to write myself and remember if it's 2 commas or 3 after the command.
