New features

  • Included the Cone Ply Piece Optimization Tool desicos.cppot module (Jasper)
  • Included Ply Piece and Fiber Fraction Imperfections (Jasper)
  • Imperfection data for cone K08 used by DLR in the DESICOS project
  • Added method to the ConeCyl class to predict P1 and N1, based on empirically derived formulae. (Giuseppe and Jasper)
  • Support for plotting PPI / MSI / TI from the Abaqus GUI (Jasper)
  • GUI for cutouts (Saullo)

Bug Fixes

  • Force viewport to display thickness imperfection colors to avoid errors (Jasper)
  • Fixed method Study.add_cc_from_DB() (Jasper)
  • Many bug fixes in the original cppot module (Jasper)
  • Do not apply imperfections: MSIs (geometric) and TIs (thickness); before other imperfections (Jasper)
  • MSI parameter r_TOL would not be applied for 'theta_z_imp'-imperfection files (Jasper)
  • Imperfection files shown for Mid-Surface and Thickness Imperfections were mixed (Saullo)
  • Load asymmetry angle (betadeg) read directly from the UnevenTopEdge instead of ConeCyl (Saullo)
  • An unexplainable bug with cutouts studies with a growing cutout along the different models (Saullo)

Enhancements

  • Mesh around cutouts and along radial edges (Jasper and Saullo)
  • Property around cutout to allow quick modeling of local reinforcements (Jasper and Saullo)
  • Automatically move perturbation load to cutout edge when they overlap (Jasper)
  • Many improvements in the original cppot module (Jasper)
  • Updated cppot documentation (Saullo)
