How may I enable the GPU acceleration in HFSS?

  Is there anyone can help me with the GPU acceleration in HFSS?
  
  I enabled the option but I got this error message.
  
  Here is my configuration, I've contaced the computer support of our department and they confirmed that the new graphic card they're using supports the GPU acceleration.
  
  Is there anything wrong with my configuration, please? Or what the problem may be?

  Take a look at the attached screenshot - uncheck the "Use Automatic Settings" box to disable automatic settings. Also, keep in mind that GPU acceleration is only useful when your HFSS model requires greater than 256GB RAM...

  Thanks a lot, my simulations sometimes take up to 400GB of memory, while the server has a memory of 1TB.
  
  I will follow your suggestion.

  I still want to force GPU use regardless of usefulness and consumed RAM. I need CPU core for other tasks, while GPU is grinding numbers.
  
  Where is the switch which forcefully tells the solver to use GPU?
