I'm taking an Intro to CFD class, so I'm pretty new to it, but I had a quick question. I'm working on coding a "lid driven cavity flow" for fun, and was wondering if there was a way to plot the velocity vectors with arrows to show the eddys. Right now I have a contour plot to show streamlines (lines of constant psi). Also is there a way to get a finer contour plot? Here is what my results look like right now. Not sure if it's right but it looks like some photos i've seen online. Thanks!

To plot arrows you would typicall use the "quiver" function (with the same data as used in the contour plots). You can import CFD data and plot them in MATLAB with the FEATool simulation toolbox, here is a tutorial for a lid driven cavity example as in your picture: MATLAB CFD simulation tutorial for a lid driven cavity fluid dynamics model
