Extracting Frequency Response data of Cantilever Beam

I am trying to get the frequency response and deformation of a simple 2D cantilever beam that has an edge load and is fixed on the opposite end. I assigned the material as structural steel and set the physics using the ‘beam’ module under structural mechanics. For study, I used the frequency domain with a range from 1 to 1000 and under 'Dependent Variables' I have 'Displacement Field' with components 'comp2.u, comp2.v, comp2.thz' being listed as field components. Using the default mesh settings, I ran the analysis and after computing the results, when I try to export the data for plotting using Matlab, I cannot get the deformation and frequency values. Using any of the 'comp2.u, comp2.v, comp2.thz' as expressions for data under export generates an error message, 'Cannot Evaluate Expression'. I would like to know why this happens, and how I can successfully export the frequency and deformation data.
Thank you.
