Display DPM particles in Fluent

      Hi,nI am trying to display solid particle trajectories on a compressor rotor domain. I inject the particles from the inlet, which consists of 2183 cells. The particle tracking is completed, however my screen crashes every time when I try to display the particles. My PC screen crashes even for 100 particles. The Ram is 16 GB, so I believe it is adequate for these simulations. Do you have any suggestions on how can I fix the problem? Thank you.n

      Hello, nWhat is the particle track style you are using to display? Can you try with lines as the track style without continuous pulses?n

      Hi, nThank you for your help. I forgot to mention that the particle tracking is steady-state and one-way coupling. I am trying to display lines as a track style and particle velocity magnitude. I press save/display, the particle tracking is completed, however my PC screen crashes and it doesn't display the trajectories. I also tried to skip some particles, but it didn't work. Any suggestions? Thank you.n

      Yes, I can display air velocity contour for example.n

      Can you please try the following : nLoad the case and data to a new fluent session and try to display the particles. nSetup a test case and check if you can display the particlesn

      In previous versions of ANSYS Fluent, 3D arrows for vectors lead to computer crash (at least in my computer). In regards to particles, I seem to remember that the same problem occurred when displaying particles as spheresnWhich version of ANSYS Fluent are you using? Are you displaying particles as points?n

      Hi,nI tried to load the case and data to a new fluent session, but it didn't work. The sreen crashed again.n

      I am using ANSYS 19.2. I am displaying the particles as lines. n

      Can you complete a particle track, ie track rather than display? That'll confirm it's graphics over something else. n

      Yes, I can track particles without displaying them. The problem appears when I try to display them.n
