*INTERRAO

Data format:

A single line with one value.

IOPR IOPC

Restriction :

For dynamic analysis.

Purpose :

To define interpolation of the RAOs of motion of all floaters in the analysis or interpolation of the current direction

Details :

Parameter	Description
IOPR	- IOPR = 0 : interpolation in direction on the amplitude considered as real number and phase considered as complex number - IOPR = 1 : (amplitude/phase) is transformed into complex number and the interpolation is performed on the complex numbers directly
IOPC	- IOPC = 0 : Current direction is interpolated linearly based on current heading of depth above and below the point considered - IOPC = 1 : Current direction at depth above and below the point considered is written as a complex number and is then interpolated linearly
