Calculate added resistance RAO using DTU method
This method was developed at DTU to compute added resistance using hull dimensions for different ship speeds and wave directions. It is based on strip theory, Faltinsen's method for short waves and WAMIT calculations for zero forward speed cases. The DTU method can compute the added resistance for wave headings from head sea to beam sea. Added resistance is considered zero for stern quartering and following waves. Further details and validations can be found here. This method works for froude numbers less than 0.25.
