I have a similar query as the discussion above. I am simulating the dispersion relations of an elastic solid. I want to filter out modes in my 1D plot, e.g., show only flexural modes. To do this, I want to apply a filter subnode to my 1D Global plot node. What expression should I use in my filter node?
I am unable to access variables like u,v,w. Kindly advise.
Thank you, Mohit.

For a simple case, you can probably deduce it directly from the modal participation factors.
For more complicated cases, you have to set up integration coupling operators, where you create some type of measure based on domain integrals of the mode shapes.
