Plot Modes of a cylinder in 3D

Up above is the modes of a cylinder stretched out flat for 200 degrees around the cylinder. Data is arranged in a 3D matrix: Distance x angle x displacement(at a particular time step).

The amount of data taken covers 200 degrees of the cylinder. I would like to show this data on a cylinder instead of it being flat. So far I have converted the polar data to cartesian however I am unsure how to plot this data onto a cylinder for 200 degrees.

Will I need to zero the remaining 160degrees as I do not have data for this?

Thank you :)

So once I have built the cylindrical mesh to my required dimensions, how is the data I have collected plotted to those mesh coordinates?

[KSSV]

That depends on how and what your data is.

[ELizabeth Sharp]

The data is angle of rotation, the distance down the cylinder and the displacement/time collected at each point.

[KSSV]

How the displacements are?

[ELizabeth Sharp]

Apologies, I don't understand what you are asking?

[KSSV]

How you got dispacements? Arrange them and plot. Refer this : https://in.mathworks.com/matlabcentral/fileexchange/32719-postprocessing-in-fem

Thank you so much! I have read the extra files and these seem perfect for the application :)

Unfortunately I am having some issues with the code:

Arrays have incompatible sizes for this operation.

Error in main (line 43)

U = sqrt(UX.^2+UY.^2+UZ.^2);

The components of displacement for x and y were 41x58, the cylinder was scanned in 5mm by 5 degrees squares around from 0 to 200 degrees. So I have reordered the x and y arrays to 2378 x 1.

However the z compnent is 0:5:285. This is 0mm to 285mm in 5mm steps.

I am aware the array dimensions disagree however this is the data structure.

Using your mesh generation code I have applied the data to a surf plot, without the deformation.
