1.20

You are here:
  • Major overhaul with lots of new features:
    • New calculations: length/beam ratio, longitudinal center of buoyancy, longitudinal and lateral righting arms, midships coefficient, wetted transom area, entry angles and aft run angle.
    • Experimental hydrodynamic resistance prediction calculation using KAPER and Holtrop algorithms. More algorithms might be added in the future. The resistance data can be viewed in a graph and exported to .csv or .png files.
    • It is now possible to adjust fluid density in the Settings window (fresh water, salt water or other mediums).
    • In case there are multiple underwater bodies (multihulls, disjoint appendages, etc.), it is now possible to combine their hydrostatics, or analyze just the largest underwater body.
    • It is now possible to export any of the hydrostatics into the Graph window. Additionally, these values can now exported into the graph after the calculations are complete, so you don’t need to re-run calculations to view a different hydrostatic graphically.
    • Added an iteration counter in the Main window for a precise estimation of the number of results.
    • In Iterate Through Heel mode, it is now possible to auto-adjust the trim to keep CoB and CoG in the same lateral plane.
    • FLOATSOFT will now automatically check if there is a newer version of the application on www.floatsoft.net, and inform the user if an update is available.
    • You can now now submit bug reports, questions or feature requests directly from within the application by using the Feedback button in the Main window.
  • Changes:
    • FLOATSOFT will not use SOLIDWORKS Front, Top and Right Planes anymore. As a result, some calculations and measurements show a performance increase by as much as 82%.
    • Re-wrote the core code of Solidworks Body manipulation. Depending on a hull, you should see an additional performance improvement up to 47%.
    • The calculation results in the Main window are now displayed in a table, rather than plain text. This table can be scrolled, resized, copied, etc.
    • The Graph and Resistance windows can now be dynamically resized by clicking and dragging on the edges with the mouse, as well as maximized. The Main window can be stretched sideways in the same way to avoid needless scrolling through results.
    • Changed the order of some of the hydrostatics for more logical grouping.
    • Changed the naming of some of the calculations to make them more intuitive.
    • Removed Maximum sectional area and Maximum sectional area distance from the selectable calculations, as they are now redundant.
    • In the Units selection, renamed Newton-feet to foot-pounds and Newton-inches to inch-pounds, as these are more commonly used in the Imperial measurements system.
    • Maximum draft indication (and the check of the input draft versus maximum draft during Solve with known draft mode) now takes heel and trim angles into account.
    • Configuration and memory files are now stored in separate folders from the main executable to reduce file cluttering. 
  • Bug fixes:
    • Fixed incorrect trim sign being displayed in the trim input box in Simulation mode.
    • Fixed a bug that sometimes caused calculations to fail with a message “FLOATSOFT failed to perform a required operation with this hull model…[]”
    • Fixed a bug when the application would sometimes get stuck when testing a hull at a 90° heel or trim angle.
    • Fixed a bug when the application would sometimes miss the last iteration in Iteration modes due to floating-point error.
