Record (17b), Incident Wave Frequencies for Integration of Ship Motion
Spectrum
One of Records (17a) or (17b) must be given.
“waveFreqs”, waveFreqs (1 character string, array of floats)
“waveFreqs”
Record tag.
waveFreqs
Array of increasing incident wave frequencies (rad/s).
Record (18a), Wave Direction Range for Integration of Ship Motion
Spectrum
If spectrumOption in Record (13) is set to CosSpectrum or DirSpectrum, then
one of Records (18a) or (18b) must be given.
“waveDirFromRange”, waveDirFromDegMin, waveDirFromDegMax,
waveDirFromDegInc (1 character string, 3 floats)
“waveDirFromRange”
Record tag.
waveDirFromDegMin
Minimum wave direction (deg).
waveDirFromDegMax
Maximum wave direction (deg).
waveDirFromDegInc
Wave direction increment (deg).
Note:
Wave directions are given using a convention of 0◦ for
waves from north, 90◦ for waves from east.
Record (18b), Wave Directions Integration of Ship Motion Spectrum
If spectrumOption in Record (13) is set to CosSpectrum or DirSpectrum, then
one of Records (18a) or (18b) must be given.
“waveDirsFrom”, waveDirsFromDeg (1 character string, array of floats)
“waveDirsFrom”
Record tag.
waveDirsFromDeg
Wave directions for integration of ship motion spectrum.
Wave directions are given using a convention of 0◦ for waves
from north, 90◦ for waves from east.
Record (19), Beginning of Steady Forward Speed Sinkage and Trim
Data
Records (19) to (19b) can optionally be used to give ship sinkage and trim data.
“begin steadySinkageTrim” (1 character string with 2 words)
