New features

General, modelling

• Parametric 2D-modelling introduced. Y/Z-grid positions and main particulars like B, D can be used in several modelling dialogues for geometry, plates and stiffeners where a coordinate is entered.
• Filtering possibility added to workspace list, list of rule calculation files, stiffener profile list and end connection/shear connection list. The filter option will shorten the list to ease the selection of the proper item.
• Modification of spacing between multiple longitudinal stiffeners is now possible.
  

Finite Element Assessment

• FE Fatigue Tool: Low cycle fatigue assessment, as required for gas-fuelled container ships introduced
• Local Model Load Applier (LMLA) Tool: For supports of independent tanks, contact forces represented as nodal forces in the cargo hold model can now be distributed as surface loads (lateral and traction) in the local model
• Export to GeniE: Transverse bulkheads modelled in Nauticus Hull can be exported to GeniE
  

3D Beam

• Tapered beam profiles: Users can create beam profiles with linearly varying cross-sectional dimensions along the length of the beam, that will be taken into account when computing stresses
