Hi all,
I'm trying to write a journal file to be used in a remote HPC about a transient simulation. I know how to write it and how to obtain a *.dat file for each time step but I'm looking for a way to obtain a *.dat file which include all the time steps. Is there a way to have all the time steps within the results panel? In few words I would like to merge all the *.dat files in a single *.dat file. My purpose is to plot the temperature trend during the simulation in a specific point of my geometry. Thanks Mike |

Hi AlexanderZ,
first thanks for the reply and second can you explain better how I can use monitors in a script? I'm using TUI command for my remote simulation. The script I'm using is this: ; Read case file rc mycase.cas ; Initialize the solution /solve/initialize/initialize-flow ; Set up auto-save /file/auto-save data-frequency 1 /file/auto-save append-file-name-with time-step 6 ; Time step size 0.5 sec /solve/set/time-step 5e-1 ; Iterations per time step 10 and 1200 time step /solve/dual-time-iterate 1200 10 ; Write data file wd myresults.dat ; Exit FLUENT exit yes Thanks again Mike |

Open your case (on local machine or cluster, up to you),
create points at locations you are interested in, go to monitors and create surface monitor of temperature (for instance), choose Write option and define file name, save your case, run it, using journal Best regards |

thanks AlexanderZ! your help is very useful!! I've just setted up the monitors and it works!! another doubt is which surface report I have to choose (area, facet average,...) I created a point in my dominium and I would like to know the temperature value on this point. I tried with the vertex average but I obtain completely different values from sperimental data...may you help me! my mesh type is quite regular and I have mostly hexa element. your help is really appreciate
regards, Mike |

Hello there,
does anyone know how to alter the above TUI commands of the journal file in order to include adaptive time stepping instead of a fixed one? Thank you very much in advance |
