SHIPFLOW BASIC
Calm water wave resistance fast, accurate potential flow analysis for hull design
Potential Flow and Thin Boundary Layer Method
Potential flow methods are a very powerful tool for optimising, for example the forebody of ships. The power lies in the accuracy in ranking design modifications in combination with the short computation time. The short computation time makes it possible to try many different variants or to set up a parametric optimisation that will finish within reasonable time.
Combining the potential flow method in XPAN with frictional resistance from the thin boundary layer method in XBOUND will include the viscous effects.
XPAN – Potential Flow Solver
- World’s most efficient free surface potential flow panel method
- Non-linear free surface boundary conditions
- First or higher order panels and singularity distributions
- Non-lifting or lift-generating appendages
- Computes waves, wave resistance, lift, induced resistance
- Dynamic sinkage & trim and pressure distribution
XBOUND – Boundary Layer
- Computes the thin boundary layer on the hull
- Momentum integral equations
- Small cross-flow approximation
- Laminar and turbulent flow
- Transition computed or fixed
XMESH – Mesh Generation
- Creates mesh used in XPAN and XBOUND
- Uses IGES, STL or offset files as input
- Various hull configurations: monohull, catamaran, trimaran, twinskeg.
Reporting
- Automatically generated report in HTML format
- Created after each SHIPFLOW run
- Customizable standard images and tables
- Format similar to tank test reports for easy comparison
