Hi,
The results from a frequency domain analysis are complex valued, so that they contain phase information. What you see is as a default the real part of the quantity. You can for example try plotting solid.sx, real(solid.sx), imag(solid.sx), abs(solid.sx), and arg(solid.sx) to explore this.
Note that the phase angle at which the results are presented can be changed in the settings for the data set, using the field 'Solution at angle'. The value used in the expressions above is actually solid.sx*e^(i*phase), where the default value for 'phase' is zero, unless changed in the data set.
