I have a problem with the black screen in fluent (ANSYS Workbench: Academic Student Release 19.2):
Changing the color scheme was not solving the problem.
The intel graphic driver is updated
• I have no NVIDIA graphic card, only a Intel Iris Plus Graphics 640 (Surface pro).
• Display Resolution: 2736x1824
• Win10, 8gb RAM
I don´t have “Intel Graphics Driver Control panel“, so I can´t disable the "Multi-Sample Anti-Aliasing" (I saw this solution in a other thread)
Is there someone who can help me?

The graphics in Fluent are demanding and Iris is not supported and not a mean to work with Fluent. Please try to start with the flag "msw".Using msw instead of opengl instructs ANSYS Fluent to use the Operating Systems Windows driver rather than the hardware OpenGL driver.

Hi I have the same problem too but I can not find where can I flag the "msw"

I think you need to add -driver msw into the environment variables in the launcher panel: I can't easily test as my machine works..... I've also only ever done this on an old UNIX box about 15 years ago and that used command prompts to launch everything.
An alternative will be to disable the graphics in Fluent via the text interface and then restart them using the msw option. This is described in Section 33.1.7 of the R19 User's Guide; replace opengl with msw.

I used to work fine with 19.2 but i dont know why Fluent became "black screen"
I have the exact same computer, configuration and the same "black screen" problem in ANSYS Academic 19.2 with Josh. But after going through all articles regarding this, I still can't figure out how to solve it, especially the "msw / opengl" idea.
Can someone please help?
Thank you so much.
