Cubit Learn on Windows server

Howdy all,

I would like to use Cubit on a Windows server but when I start the program, the graphics window is disabled. Is there an option in Cubit or Windows (Server 2012) that anyone can suggest I look into? I’m using Cubit Learn 2020.2. Thanks.

David H.

Dave,
One of our IT gurus will get right back to you.
I don’t know the precise answer, but these issues usually end up with an OpenGL setup issue.

@scot @kaleb - Any suggestions?

@david.holler Can you open up a cmd prompt in your Cubit installation’s bin folder and execute these instructions please:

set CUBIT_VERBOSE=5
coreform_cubit.com

Please paste all the output here.

Hi Scot, I have attached the output below.

[2021-02-23 14:50:55.644] [error] Could not find ARB attribs

@david.holler That error “Could not find ARB attribs” means that your graphics driver doesn’t have features that Cubit requires. Could you please try updating your graphics drivers? Does that server instance have a dedicated graphics card? We’ve had issues with integrated graphics in the past.

I don’t know if this is applicable and it is old, but it also shows that others have had issues with OpenGL on Windows Servers in the past.

Good morning all,

Thank you for your input. This issue was resolved by updating the graphics drivers and installing the latest version of DirectX. The Windows 2012 server in question has a NVIDIA GeForce GTX Titan X graphics card.

David H.

Howdy all,

Since my Cubit install works, I’d like to help it perform the best I can. Are there any ways to improve Cubit performance on Windows or Windows server platforms? Does parallel meshing work for the Cubit Learn version? My Windows server has a lot of memory that can be put to use. Thanks and please let me know if I can provide further information. Thanks.

David H.
