I'am setting up a WVD environment with Windows 10 21h1 with a NVIDIA Tesla M60 as videocard, Fluent 2021 R2 is installed.
After starting Fluent 2021 R2 the Fluent Launcher starts, after choosing Start i see 5 seconds a splash screen of Ansys 2021 and then the application crashes. Can't find any application logfiles in %TEMP% or C:windows emp or other folder. There is also nothing in de Event Viewer logs.
Where to find the logfiles? Can this application work on a Windows Virtual Desktop?
THNX!January 7, 2022 at 9:27 amRobForum ModeratorCheck the working folder for a trn file, that may show something but tends to need the solver to start to give anything. Can you post a screen shot of the Fluent launcher panel?

There is nothing in the Working directory. Created for test a other folder but the folder remains empty.
Working folder is the same as the Working directory?
January 7, 2022 at 11:01 amRobForum ModeratorCorrect, can you confirm the userID is all letters/numbers with no "odd" characters? What are the parallel settings?
January 7, 2022 at 12:04 pmJanuary 7, 2022 at 12:08 pmbert_itwSubscriberThere are 2 IP Interfaces to select; 127.0.01 (localhost) and host IP. Also tested with the other parallel settings.
January 10, 2022 at 2:57 pmbert_itwSubscriberdo you have a solution for this?
January 10, 2022 at 4:02 pmRobForum ModeratorNo, it'll need or 's input - I drive the software, they understand how to make it work.

Tried al the 3 options but it still crashes at startup.
After installing the Microsoft lookback adapter, the adapter get's no IP because there is no DHCP server. So its getting 169.x.x.x, is that a problem?
In our environment its also not possible to automate the installation of the Microsoft loopback adapter.
January 14, 2022 at 5:08 pmGeorge KarnosAnsys EmployeeNext i would check the Graphics card and driver.
What graphics card do you have and make sure that the driver is up to date.

April 27, 2022 at 2:55 pmBenMartinBaurSubscribercan you confirm Ansys is running on Windows 10 Multi-Session?

Im a recent ansys user. I ve been using it for a course im taking in mechancial engineering maste´s degree.
Ansys has been working really well (i've used it with steady-thermal and static strutural) but now i was going to get into fluent but im getting the error "Fluent failed to start".
