Export streamlines from Fluent to Gambit
Hi,
I would like to realize a meshing with the streamlines. So, I would like to know how can i export the streamlines from Fluent to Gambit. Cheers, |
Hi,
You can do the following for inviscid flow. It also works for, say, k-epsilon, however I'm not sure it would be correct in that case. display > contours: velocity, stream function this will show streamlines; adjust range and choose the value of stream function for the streamline you want surface > iso-surface: velocity, streamfunction, from zones: fluid enter the stream function value plot > xy-plot: grid, y-coordinate, surfaces: the new iso-surface now write this to a file Finally, adjust the file header such that you can read it as icem input in gambit Good luck! |
Thank you for your help, I just have a last trouble. When I try to import the file to Gambit, I receive this message " Error : Error reading number of points per curve and number of curves". I do not know what I have to do. Maybe I make a mistake on the plot XY part.

Hi, unfortunatly you will have to adjust the file and it's extension. To do so, open the file in a text editor. You will see some lines of text followed by an array of coordinates:
============================= (title "Y-Coordinate") (labels "Position" "Y-Coordinate") ((xy/key/label "stream-function-6") -3 0.0488679 -2.8 0.0488681 -2.6 0.0488685 ============================= Replace the lines of text with the number of coordinates per streamline, followed by the number of streamlines: ============================= 3 1 -3 0.0488679 0 -2.8 0.0488681 0 -2.6 0.0488685 0 ============================= Here I have also added zeros for z-coordinate. This might be necessary for gambit, you'll have to try. Finally, the file extension should be ".dat". Now you can import it as icem in gambit. I hope this is helpfull, it's a bit of a detour but it should do the job. Hope it works, good luck! |
That works !!! Thank you so much.
