Bug Fixes

  • Implemented a workaround to address an Excel issue in a recent update which prevents Orca3D Marine CFD reports from generating plots.
  • Fixed a bug in the scriptable version of the hydrostatics command, OrcaHydrostatics, in which the initial float plane height for a free-float calculation defaulted to 0 which could cause the calculation to fail.
  • Modified the computation of the Holtrop-Mennen stern coefficient to be more robust in handling atypical stern geometries.
