The information input in these data categories is dependent on the type of analysis and the external forces acting on the structure, additional to those due to wave diffraction or radiation. Additional hydrodynamic coefficients may also be required for analyses involving drift frequency and nonlinear current/wind forces.
These fall into the following categories, any or none of which may be required for a particular analysis (see Default Values Assumed by the Program):
accuracy and conditions of analysis, e.g. initial position of structure
hydrodynamic coefficients for drift frequency forces or nonlinear current/wind forces
environmental conditions of current, wind, waves
external constraints of mooring lines or articulations
hydrodynamic coefficient multipliers for parametric studies
