Actually I was working on the “Cylinder3D”, where I created the model by Freecad. The model was a little bit large in size. I extended the Y-axis from 410 mm to 2000 mm. The Grid size becomes around 500 million. Sometimes it gets aborted or Killed. When I try to run it in GPU, I am getting this problem. :

I dont understand what is the issue. Is my system not able to handle the simulation or any other problem?
Please help.
