What do you like best?
Firstly, this is the only FEA I've used that uses multiple threads/cores of a CPU, which streamlines calculation time significantly, in my experience. Secondly, there's pretty much nothing you can't simulate, seriously. With the workbench, running beam analysis, thermal transfer, fluid flow...you can do all of this to the same part. It's very integrative.
What do you dislike?
If you haven't been trained on it, it's very overwhelming. This thing needs a 40 hour course to fully understand how to properly prep for Analysis, set up your part or assembly for Analysis, mesh, and finally run the analysis. Just understanding the consequences of how you're running your analysis and what your results look like can be a bit complicated.
Recommendations to others considering the product
This is a complete solution. If you're in the engineering or manufacturing industry or rely on them for product conceptualization and time to market, you need some type of FEA software, especially when your competitors are already using it!
Take the training, get involved, and start using it immediately! I had a "re-learning" curve as the time between when I took the training and when I started using it was significant, and it's definitely a perishable skill.
What business problems are you solving with the product? What benefits have you realized?
FEA helps to streamline the product development process by allowing you to simulate real-world stresses and implementation when used as intended, and what the robustness and durability of your product is as designed. This will help you get your product to market faster (as it'll cut down on prototype iterations you'll need), it'll help you prevent over-engineering, which can mean more cost and lead-time, and it is all presented in a very robust way.
