*Regular Wave Equivalent

Previous pageNext page

Purpose

To specify that Flexcom is to replace a random wave spectrum or spectra by an equivalent regular wave or waves, and to calculate equivalent sinusoidal boundary conditions for attached nodes.

Theory

Refer to Equivalent Regular Waves for further information on this feature.

Keyword Format

One line of data specifying the wave period and height coefficients.

[Period Coefficient] [, Height Coefficient]

The keyword is only valid in time domain random sea analyses containing at least one vessel and one attached node. No sinusoidal boundary conditions should be specified.

Period Coefficient defaults to 0.95. Height Coefficient defaults to 1.86.

Table Input

Description

Factor for Wave Period:

The factor to use in calculating an equivalent regular wave period from the wave spectrum peak period. This defaults to a value of 0.95.

Factor for Wave Height

The factor to use in calculating an equivalent regular wave height from the wave spectrum significant wave height Hs. This defaults to a value of 1.86.

Notes

(a)The random sea analysis must contain at least one vessel and one attached node.

(b)No sinusoidal boundary conditions should be specified when using this option.
