Ansys is such a powerful range of software but the guides on all features are basically non existent. (The tutorials do not count).
My experience working at large size company that paid those sort of sums for a different FEA software is that we got an "application engineer" assigned to us to answer any questions we had and provide needed documentation if anything was needed. He actually sat and worked from our own offices one day per week.
Once again, this isn't a huge expense compared to the license cost + the engineer's salary.
Then for ongoing support/questions you get the support I mentioned including the onsite support engineer.
