I am doing DPM analysis of a spear and nozzle having 11 million mesh elements, I solved in HPC but How can I visualize particle tracks or injection as when I do in fluent workstation it took very long time with DPM iterations. I want it to do in HPC using bash script file or any other method how can I do it so that I can visualize it in my system.

You can run in batch with TUI commands in a journal file to generate a picture of the tracks. But it is not ideal as you have to choose some orientation and the picture is only for that orientation. Also, the picture quality depends on the software rendering on the HPC. Ideally you want to run interactively so you can rotate the display. There are 3 options

 

1) If the HPC has graphics capability and provides a display on the HPC you can run interactively on the HPC. For Windows HPC it may provide a remote desktop capability. For Linux HPC it may provide a VNC capability to give you a Linux desktop inside a VNC client on your windows machine.

 

2) If no such graphics capability is provided and the HPC is Linux you can run a remote session via the remote tab of the Fluent launcher. This will cause the user interface to run on your windows machine and the solver processes on  the HPC. It requires you to set up ssh on Windows so that you can ssh to the HPC with no password. Essentially, you generate a public private key on windows and add the public key to the ~/.shh/authorized_keys file on your Linux account.

 

3) Fluent has a new web interface capability. You launch Fluent (or submit to the HPC job scheduler) with no user interface (-gu) on the HPC with a command option to start the web server. Then you can connect to the Fluent session from any machine with a web browser. See
