How to visualize numerical field data (velocities) in MATLAB
 

Hi fellow members
I have calculated 2D velocity field on a rectangular domain in which I would like to visualize in MATLAB the boundary layer and gradients including boundary layer thickness. Could any one please guide regarding that?

What kind of problem do you have? Just load the matrix in matlab and use the contour/plot/quiver functions.

You can visualize the boundary layer by the contour line at 0.99Uinf value.

I only have grid coordinates and corresponding u velocities. I want to see the boundary layer and of course see the thickness and points as needed. I am attaching the file though.

i doubt the file got attached. let me attach again. oh it says the file is big. it is a 4+ MB file.but any hypothetical data in columns xcoord,ycoord,u-velocity can be used.
