  I am currently using a Linux system (on the university supercomputer) to run ANSYS Mechanical (v20.1). However, when I try clicking on geometry or model it is unable to start mechanical editor or design modeler. I have tried reinstalling the software but to no avail. While I referred to some previous threads which suggest renaming a folder in %appdata%, I am unsure as to how to proceed in a Linux based system.

  This is likely a graphics issue, so resetting the 'appdata' will not help.
  
  Is there any visualization node with good graphics card installed/setup on this cluster ? Here is the list of supported/tested graphics cards

  If there is no node with good graphics, you can try software rendering mode but I can't guarantee that it will help
  
  export LIBGL_ALWAYS_INDIRECT=1
  
  export LIBGL_ALWAYS_SOFTWARE=1
  
  export LD_LIBRARY_PATH=/ansys_inc/v201/Framework/bin/Linux64/Mesa
  
  /ansys_inc/v201/Framework/bin/Linux64/runwb2 -oglmesa
  
  If this still doesn't work, you will have to do pre/post processing on a laptop, ideally with graphics card, then just use the cluster for solving (but need to use batch command to submit the jobs)

  Thank you very much for your suggestion. I tried using the software rendering mode but it didn't work. Do you happen to have a reference for how the code for submitting the jobs in batch mode for clusters would look like for ANSYS Mechanical?

  You can refer to the batch command from Chapter 4 of this guide
  
  https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v201/en/ans_dan/dan_config.html
  
  but it can't tell you exact command for your cluster submission because there are various job schedulers and each cluster setup is different depending on how your admin set it up. So, I would recommend to consult with your cluster admin on cluster submission command , then incorporate that with ANSYS batch solve command from the guide above.
