Summary
This document presents work carried out to present further validation to AquaSim users concerning the numerical sink-source algorithm used in AquaSim for calculation of hydrodynamic quantities. This document also describes some minor modifications in the analysis and result files.
The following should be noted:
- Estimating hydrodynamic quantities from the panel method can be useful and can be applied to analysis.
- In the cases studied in this document, there is obtained good correspondence between numerically and analytically calculated added mass, hydrodynamic damping and excitation forces, both horizontally and vertically, for the periods that have been considered. Note that for the cases considered in this document, analyses are carried out using regular waves.
- Results are based on numerics and does not include the effect of current and/or forward velocity.
- If irregular waves are considered, the mean zero crossing period of the spectrum (Tz) is used as basis for the calculation of added mass and hydrodynamic damping.
