Cubit CLI options: `nographics` vs `nogui`

Coreform Cubit
#1

Coreform Cubit Version: 2026.6
Platform: Ubuntu 22.04.5

I’m trying to understand the difference between the -nographics and -nogui options in the Cubit CLI. In the CLI docs, it says the following:

Command Description
nographics Run CUBIT without graphics. This is generally used with the -batch option or when running CUBIT over a line terminal.
nogui Run CUBIT without the graphical user interface.

Using -nographics in >=2026.6 seems to result in the Qt errors on headless machines, as has been documented in a number of other forum threads (e.g., here or here). I’m able to avoid this by passing in the -nographics option on versions <=2025.12 or with -nogui on >=2026.6. Using -nographics in newer versions of the Cubit CLI does not seem to do anything.

I have two questions related to these commands:

  1. What is the difference between -nographics and -nogui?
  2. Has the usage of -nographics changed in version 2026.6 compared to previous versions?

Thanks in advance for your help :slightly_smiling_face:
