How to fix the jiggly issue

I am post-processing Abaqus data on Matlab. Overall the data looks good, however, in some areas it seems to be jiggly.

I've looked up for the causes, but couldn't.

Help me please.

median filter, or low pass filter ?

Hi @FEM_Duck, There can be many reasons for jiggly or noisy data, inherently its becuase of the data that you have, Kindly provide tha data that you are using for better understanding.

The reason why your data contains noise usually depends on the data collection method and will require an investigation on that part. If you wish to filter the noisy datapoints in post-processing, you can use the Smooth Data task in a live script.

Open a new live script, insert the Smooth Data task from the Live Editor tab, and adjust the settings until you get an acceptable result.

You can then click “Show code” on this task to obtain the corresponding MATLAB code, and move it from the Live Editor to any MATLAB script.

For more information, refer to the “Smooth Data Task” documentation: https://www.mathworks.com/help/matlab/ref/smoothdatatask.html

Hope this helps!

Hi,

The red datas are from Abaqus Shell analysis. I don't know why only the right half has that jiggly datas.

It would help if you were to attach the data

attached! The Abaqus data seems to have some errors, maybe?
