I’m looking at the OC3 results (LC 5.1 with regular 6m waves) and I have a question about the WaveElev output. I can’t seem to find this output in the manual anywhere so I’m asking on this forum. In the results it says, in the variable description, that WaveElev is "Wave Elevation at Platform Centerline ". Does that mean it’s measured at the moving tower? Looking at the signal (and an FFT) I see only the wave frequency in its content. However, if it was moving with the tower I’d expect to see, at the very least, the surge and pitch frequencies in its content, so I’m assuming that this output is actually measured at a fixed point (probably the initial point at the SWL?). Can someone verify and/or clear this up for me?
