SHIPFLOW MOTIONS
Seakeeping program – Time accurate CFD solver for ship motions and added resistance
Seakeeping Simulation
Time-accurate CFD solver for ship motions, added resistance, and wave-induced response
Flow Solver for Computing Ship Motions in Waves
It is a time accurate fully nonlinear boundary element method which can be used to compute ship motions and added resistance in regular and irregular waves as well as wave resistance, sinkage and trim in calm water.
Typical results are time series and response amplitude operators. We believe that the method will be a useful tool for ship designers with better accuracy than traditional potential flow methods while at the same time being faster than the available RANS methods.
XPTD – Time Accurate Solver
- Time accurate free surface potential flow panel method
- Fully non-linear free surface boundary conditions
- Calm water: waves, wave resistance, dynamic sinkage and trim
- Regular or irregular waves: added resistance, motions and accelerations
XMTD – Mesh Generation
- Creates meshes used in MOTIONS
- Uses IGES, STL or offset files as input
- Various hull configurations: monohull, multi hull and twinskeg
Reporting
- Customizable standard images, movies and data output
- Created after each SHIPFLOW run
- Format similar to tank test reports for easy comparison
Applications
