Hull University,
Thank you for your questions. The WECCCOMP organizers’ responses are below:
1. The value for Z_{max} is 0.06 m (6 cm), please use this value for calculating the evaluation
criteria.
2. A validation study was completed that included a linear rotational damping term to tune the
WEC-Sim model to match experimental measurements of the Wavestar. The
wecSimInputFile.m was modified to include a body(1).linearDamping term that was
determined from experimental tests. This term includes the combination of bearing friction
and fluid viscous damping. Please pull the latest version of WECCCOMP from the Github
repository.
Thank you again for your questions, if you need additional clarification, please post to the forum and the organizers will respond as quickly as possible.
Cheers,
Nathan Tom
