Hi, so I had the same problem regarding the black screen when you start Fluent. It took me a while, but I believe that I found a solution. Most probably you have two video cards: intel (integrated) and NVidia as dedicated. Apparently, fluent does not use NVidia as default video card. If I press second mouse button on fluent>Run with graphics processor>High Performance NVidia , it works fine. I have manually changed the default graphics card and for the moment everything looks fine.
