Hi there

We were re-running some basic verification steps, namely the RM3 WEC-Sim model using the provided WAMIT data and an equivalent model with nemoh data.

Using the same wave heading, we noticed that the angular response and exciting moment time series are 180deg out of phase (between the WAMIT and nemoh related models). The phasing issue does not emerge in the translation modes.

We were wondering if this has been experienced by other users? Changing the phase associated with the diffraction problem in nemoh ('Compute_Wave' routine) allows the phase alignment to occur, but if this a regular issue perhaps there is potential to adjust it directly in WEC-Sim?

Thanks for the feedback
