I installed the new Ansys 2020R1 but CFD-Post shows me black screen.
At first i thought it would be problem with the rdp-connection i use.
But today i am at work for the first time in 3 weeks and had the chance to test this at multiple machines.
I noticed that i got a black screen at a PC with a Nvidia GT640, ATI6850, Intel 4600, but a newer machine with a Intel UHD Graphics 630 worked, even over rdp.
I updated all graphics driver no change. I set a varibale QT_OPENGL/desktop, cfd-post won´t even start.

I solved it... it is a very strange bug.
You must start Ansys (CFD-Post) local on the PC not over Remotedesktop. If you can´t get to the actual PC, you can use VNC-Server(as a service) und VNC-Viewer ( i used UltraVNC) to start Ansys CFD-Post. After that you can use a Remotedesktop connection and there will be no black screen... .
Moreover it didn´t work if you have installed more than one Ansys-Version. I deleted all Version and installed only Ansys 2020R1.
If you close the rdp-Connection and open it again, than you have a black screen again.
Why the bug didn´t appear on a new machine, i have no clue.
