Hi,
So Im not sure how to approach this. Basically, I was given an access to supercomputer but it is asking for something like fluent 3d -t 1 -g -i elbow.jou > output_file or batch system or sort. So basically I run record a journal but i couldn't load the file and is it giving me an error saying job.jou couldn't find but its clearly there. Basically I just want the supercomputer to load fluent 19.1> initialize > run calculation. That's all. I have pre set the time step size and time step and the auto save on that files. Please help! /file/set-tui-version "19.1" (cx-gui-do cx-activate-item "MenuBar*ReadSubMenu*Case & Data...") (cx-gui-do cx-set-file-dialog-entries "Select File" '( "starting.cas") "Case Files (*.cas*)") (cx-gui-do cx-activate-item "Ribbon*Frame1*Frame5(Solving)*Table1*Table3(Initi alization)*PushButton5(Initialize)") (cx-gui-do cx-activate-item "Ribbon*Frame1*Frame5(Solving)*Table1*PushButton1( Run Calculation)") (cx-gui-do cx-activate-item "Ribbon*Frame1*Frame5(Solving)*Table1*Table3(R un Calculation)*PushButton7(Calculate)") (cx-gui-do cx-activate-item "Information*OK") |

Sorry it's hard to understand what your issue is. Maybe let's take it one issue at a time. Nothing you write makes any sense.
First, are you able to launch and do anything in Fluent? clusters often have job schedulers and you submit jobs to the cluster using a script specific to the job scheduler (i.e. torque vs batch vs oracle vs sun grid, etc). Now assuming you have that part figured out... Who runs on a supercomputer using the -t1 (one process) flag? It should be -t1000 -t10000 or something... If you're going to be doing any serious computation, learn to write a journal file using only TUI commands and don't use macro's. Especially for something as simple as initializing and calculating. To read, initialize, and run a transient case can be as simple as 3 lines (in this example, run 100000 timesteps at 10 steps per iteration) + 1 line to save + 1 line to exit: Code:
rcd blahblah solve/initialize/initialize-flow solve dual-time-iterate 100000 10 wcd blahblah ok exit ok |

Hi thanks for the response,
sorry was recently granted to using the computers by my supervisor. May I know how do you write "journal" as in where should I type the command and how do I save it as .jou. Do you have any links to those TUI commands? Thanks! Update: I think I've done it. Just sent my codes to the computer. Thanks! Last edited by Hnsie813; October 25, 2018 at 10:58. |
