I've looked at that list before. I have another forum thread open where this same thing is happening on our workstations, and this seems to be the fallback response. I realize that you can't test every card, but it seems like something as high-end as the NVIDIA A40 would have at least the minimum specs/requirements to run.
All of the workstations that we have were able to run Ansys versions prior to 19.2.
