Hi, I am new to comsol. I would like to plot results of a point versus frequency. I did have results of the domain including the point I wanted. However, when I used 1D plot->plot graph, I got an empty plot and a warning saying "The plot is empty. I am a bit comfused by COMSOL because its result is not based on element or nodal points. Does the point I pick need to overlap with a nodal point? If not will COMSOL do the interpolation?

If you pick a point like a corner on the geometry, there will be a node there. But you might be picking a point right now that is not part of the meshed geometry? You can also set up a Cut Point under Results-Datasets whose coordinates you are free to choose, and they are not necessarily going to coincide with a node.

Thank you very much. I did successfully get some plot. How can I refer to the cut point when I use 1D point plot?

Change the Dataset from Study1(...) to you Cut Point solution.
