&lt;p&gt;Are you trying to run time history fatigue from a random wave? Are you trying to generate the random wave from a wave spectrum or self-defined surface profile?&amp;nbsp; Normally for jacket wave fatigue analysis we use spectral method as the time history method would cost numerous analysis time.&lt;/p&gt;
&lt;p&gt;For your question,&lt;/p&gt;
&lt;p&gt;1 &amp;amp; 4, For a time history simulation of wave,&amp;nbsp;definitely&amp;nbsp;the time increment should be small enough and the time duration should be long enough to reflect the random characteristic of wave. This is usually determined by engineers themselves and you can refer to the design code required to follow by your project.&lt;/p&gt;
&lt;p&gt;2 &amp;amp; 6, For both spectral and time history&amp;nbsp;wave fatigue, I guess you need the same wave scatter diagram which includes the probabilities of different wave spectrums from different direction.&amp;nbsp;For&amp;nbsp;each wave spectrum&amp;nbsp;in scatter diagram you should make a time history simulation and run a time history fatigue. Then the total damage is accumulated for each time history simulation.&lt;/p&gt;
&lt;p&gt;3,&amp;nbsp;Please check 3.1.2~4 of&amp;nbsp; &amp;quot;wind turbine&amp;quot; manual for the random wave surface generation. Each seed will&amp;nbsp;generate a different surface and user should determine how many seeds shall be calculated and which one to be used.&lt;/p&gt;
&lt;p&gt;5,&amp;nbsp;SACS time history fatigue use rainflow method(ASTM E 1049-85,Standard practices for cycle counting in fatigue analysis,Reapproved 2005)&amp;nbsp;to count for cyclic stress and number of occurrence. If you want to know details, please review that reference.&lt;/p&gt;
&lt;p&gt;However, all these can be found in SACS wave response and fatigue manual and I can send you a simple sample of single time history.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
