Romain,
Thank you for reporting this issue. I have verified the problem in the current version of HydroDyn (v2.05). This bug was created when we added user supplied wave kinematics and with our wave stretching implementation. Some additional code is needed in the WriteSummaryFile() subroutine of Morison.f90. I’ve generated a fix, but it hasn’t been verified. As you state, this bug does not affect the time-marching load calculations. We will incorporate this bug fix into the next released version of HydroDyn.
Thank you,
Greg Hayman
