velocity profiles
 
Hello CFD F riends,

i am simulating natural convection in square cavity(2D) using Fluent 6.3
i d like to ask you how to draw the velocities profiles(in x direction and y direction) at the mid-width and mid-height of the cavity in order to get the maximal velocity for both x and y directions and theirs positions
please make me kown
have a nice day :)

if you want to draw velocity profiles along the lines in x and y direction on the mid plane of the cavity , just create lines using points and plot velcoity along them.(or) Create a mid plane, and plot a velocity contour and see the max velocity

Hello Victoryv ;
okay I'll try it , plz could u tell me how to create a mid plane? u mean create an endge on the middle of cavity when create the mesh (on GAMBIT?)
Thank you so much

Do this simply in FLUENT you can draw a line/rake at middle length (x=L/2) and choose y=0 to y=H then plot your profile along it. Did you solve a lid-driven cavity problem?
