I have a 2D axisymmetric contour of a converging-Diverging nozzle as shown below:
I want to turn this contour into a 3D plot, any ideas of what the best way of doing this is? I’ve tried using linspace and mesh grid but I’ve hit a brick wall.
Many thanks, Elliott

See this example
z = 0:.1:3;
r = sin(z);
t = linspace(0,2*pi,20);
[T,R] = meshgrid(t,r);
[~,Z] = meshgrid(t,z);
[X,Y] = pol2cart(T,R);
surf(X,Y,Z)

For the 2D contour, I’ve used some loops to generate the values for x and r and save them into two arrays, x and r. Can the above code be altered to use the pre-calculated values in the arrays?

I don't understand. You can use for loop or meshgrid as you wish

Sorry, i was getting a little mixed up, this worked perfectly! thank you very much!

Could you please show me how to get this 3D plot from your initial 2D countour line?
