Structural and Environmental Data |
|
All the required structural and environmental data is specified in standard Flexcom analyses. You would typically perform one or more static analyses (e.g. initial static, current static etc.) in advance of several random sea analyses, corresponding to all or selected seastates in the wave scatter diagram for each direction of wave approach. Analysing all seastates is consistent with the Stress Spectra mode of operation, while modelling selected seastates typically corresponds to the RAOs mode – the specific operation of both modes is expanded further throughout this section.
•Numerous keywords are contained in the $MODEL section, including data such as the finite element discretisation, structural and hydrodynamic properties, plus any other inputs which characterise the initial model configuration (e.g. initial vessel position, seabed properties, ocean depth etc.).
•Numerous keywords are contained in the $LOAD CASE section, including data such as environmental parameters (e.g. current and waves), boundary conditions of various kinds, internal fluid loading, and the analysis type and solution parameters.
