I was using ANSYS Fluent 19.0. It was working well, but Fluent sometimes used to starting very slow. I've reinstalled this and now I have version 19.2. It was working few days after reinstallation, but now Fluent can't start. Every component (DesignModeler, Meshing etc) is working well. CPU usage of Fluent processes during start is 0%. I've tried running it parallel but there is no difference. Mesh is loading about 4 minutes, but window is like frozen and it's impossible to click anything. Restarting PC doesn't work. Problem appears in every project, even with single Fluent component (without geometry and mesh).
Thank you in advance

Hi xtka ,
If it was working right after the installation, please try resetting the configuration by
Open CMD prompt, then issue the following command
move %appdata%ansysv192 %appdata%ansysv192.back
Does this make any difference ?
If not, what is the OS and graphics card on the machine ?

I have tried that but it does not work. I have also reinstalled graphic's card drivers but still no difference.
My OS is Windows 10 and I have GeForce 650M.

Just so that I understand your current state,
Now you can't start Fluent 19.2 at all. Does it show any error, or just stuck at some stage ? If stuck, please post the screenshot. What about 19.0 ?
Also, when you said Mesh, you meant in Workbench or in Fluent ? If in Fluent, what version ? If not in Fluent, can you try just a stand-alone Fluent ?

There is no error, it just takes about 10 minutes to start Fluent (in other words, to get green light at the bottom of Workbench window). After this time, it is hard to move geometry or even click on any option. Problem occurs in every case, component system or stand-alone Fluent.
But I have realized that I have two graphic cards - integrated (Intel) and dedicated (Nvidia). I have updated Intel drivers and now it works fine. That was the problem.
Thank you for help
