The Summary Wave Scatter feature allows you to generate Summary Database Files for seastate combinations which you have not actually simulated. Based on some selected 'reference seastates' in your scatter diagram, Flexcom estimates simulation results for adjacent seastates based on an extrapolation technique. You may then use the Summary Postprocessing Collation to collate information from all seastates.
The simulation of an entire scatter diagram in the time domain can be quite time consuming, so this is a highly efficient solution technique which can save you considerable computational time. However given the inherent approximation involved, caution is strongly advised regarding the application of this feature. The Summary Wave Scatter feature should never be used to support detailed engineering design. It can certainly be used during preliminary feasibility studies, and may be used with caution as part of front end engineering design (FEED) studies.
Further information on this topic is contained in the following sections:
•User Operation provides a series of steps for you to follow in sequential fashion. It should serve as a helpful reference guide when using the Summary Wave Scatter feature.
•Extrapolation Technique provides some background theory on the computational methodology.
The section on Summary Postprocessing Collation is highly relevant also.
•*SCATTER DIAGRAM is used to specify the wave scatter diagram, including the grouping of similar seastates into blocks and the nomination of appropriate reference seastates.
