Hello,

I simulated a case of fluid flow on an HPC cluster using Ansys Fluent 19.2 in batch mode. The simulation worked fine and since I did not have enough RAM to read the data file for post processing, I'm trying to save images of my contours remotely using TUI commands. So I use this shell command to run fluent to have graphics enabled:

fluent 3ddp -gu -t16 -mpi=openmpi -i &Name.jou >& out_$Name.log 

then I use these TUI commands to define a contour and then save an image of it:

;---Display settings

/display/views/read-views "Views" 

/display/set/contours/auto-range? yes 

/display/set/contours/clip-to-range? no 

/display/set/contours/filled-contours? yes 

/display/set/contours/global-range? no 

/display/set/contours/n-contour 30 

/display/set/contours/node-values? yes 

/display/set/lights/headlight-on? no 

/display/set/lights/lights-on? no 

/display/set/picture/color-mode/color 

/display/set/picture/driver/png 

/display/set/picture/x-resolution 960 

/display/set/picture/y-resolution 720

;---Defining contour surfaces

/surface/plane z0plane 0 0 0 0 1 0 1 0 0

;---Saving contours

/display/set/contours/surfaces z0plane () 

/display/contour velocity-magnitude 3 8

/display/views/restore-view xplus-view 

/display/save-picture "z0plane_V.png"

And all of them work fine except that the saved contour does not have any labels on its colormap(!!!), no numbers.

I tried to use /display/set/color-map menu, but it seems like that only changes the colors of the contours.

How to fix this?

Thanks❤️

Please can you post one of the images? I wonder if you've got white text on a white background.

[m.shafiee1374]

Sure, but I dont think thats the case:

[Rob]

can you add
/preferences/appearance/gfc 255 0 0
at the beginning of the above and see what you get? We moved the foreground/background options into Preferences and I wonder if that's causing a problem here. I don't have R19.2 installed so can't check here.

Can you move to a newer version and also try using Contour Objects.

Hello and thanks for your responses Using contour objects worked.
