Public Types

enum  EFileType { FILE_TYPE_VERES , FILE_TYPE_WAMIT }
 

Public Member Functions

void SetupFromFile (std::string fname, EFileType type, HullData *H)
 
void SetHullData (HullData *HD)
 
void SetTheoryFormulation (int theory)
 
void SetManoeuvreMinSpeed (double speed)
 Smallest speed [m/s] in v/u and r Lpp/u of the manoeuvring terms (the speed is held to it); must be positive.
 
void SetPhiAmplitudeHorizon (double horizon)
 
void GetViscousAddedMass (double u, double v, double r, Eigen::Matrix3d &Mat) const
 
double GetViscousSurge (double u, double v, double r) const
 
double GetViscousSway (double u, double v, double r) const
 
double GetViscousYaw (double u, double v, double r) const
 
double GetViscousRoll (double phiDot, double u=0) const
 
bool IsSkegStation (int station) const
 True when the skeg is on (WithSkeg not 0) and station is one of its stations: the eddy damping is zeroed there (MAR-0078)
 
double EddieDamping (double phiDot, double u=0) const
 
double BilgeKeelDamping (double phiDot, double u=0) const
 
double FricitonDamping (double phiDot, double u=0) const

double SkegDamping (double phiDot, double u=0) const
 
double SkegLiftDamping (double phiDot, double u) const
 
double RollAmplitude () const
 The roll amplitude of the history: the largest value of |roll| within the amplitude horizon.
 
void AddToRollTimeHistory (const double T, double RollAngle, const bool bIsMajorTimeStep)
 
bool MakeBildgeKeel (double m_BilgeKeelStartPosition, double m_BilgeKeelEndPosition, double m_BilgeKeelHeight)
 False (and no bilge keel) when a start or end station of the range has no neighbour station on both sides (MAR-0075)
 
void SetSkeg (int startSection, int endSection, const std::vector< int > &startPoints, const std::vector< int > &endPoints)
 Sets the skeg stations startSection..endSection and, per station, the first and last vertex index of the skeg (one entry per station in each vector). Call after the hull is read.
 
bool HullHasTheSkegStations () const
 True when the hull has more than SkegEndSection stations and every skeg station has more vertices than its skeg end index (MAR-0078)
 
void SetHorizontalDampingBlend (double blendSpeed, double blendFraction=0.5)
 
void SetDpDampingX (double Xu, double Xv, double Xr)
