Hi Sakshi,

To my understanding you want to create a nodal model of cyclinder.

You can use the meshgrid function to generate a grid of points in the x-y plane and then stack them along the z-axis to form the cylinder. See the below code for reference.

% Parameters
radius = 1;               % Radius of the cylinder
height = 2;               % Height of the cylinder
numCircumNodes = 20;      % Number of nodes along the circumference
numHeightNodes = 10;      % Number of nodes along the height

% Generate nodal coordinates
theta = linspace(0, 2*pi, numCircumNodes+1);
z = linspace(0, height, numHeightNodes);
[Theta, Z] = meshgrid(theta, z);
X = radius * cos(Theta);
Y = radius * sin(Theta);

% Reshape the coordinates into column vectors
X = X(:);
Y = Y(:);
Z = Z(:);

% Plot the nodal coordinates
scatter3(X, Y, Z, 'filled');
xlabel('X');
ylabel('Y');
zlabel('Z');

axis equal;
