Reply To: heave motion acting like a mirror

[mdti]

Hi @akbrain,

I assume along the horizontal axis your plot is time (s) and vertical axis shows distance in meters.

(1) To my understanding, the heave motions in the plots are shown at the centre of mass (CoM) of the body. So there is a mismatch between the vertical centre of mass of the 'reference' and 'Series 2'.

(2) At the begining of the simulation there could be some transient issue. For example, if you consider platform response after 250 s, the response of 'ref' and 'Series 2' look similar.

I hope your problem will be solved if you correct the first issue. If you have further questions, please post it here, I will try ot answer.

wish you all the best.
