Getting started with Nauticus Hull

Creating a beam

  • Easiest way to create several beams at once: beam wizard (Ctrl+W). Can be found under Tools → Beam Wizard
  • Other option is to draw with the mouse under Model → Create beam. This method is less accurate and can easily lead to mistakes.

Changing beam-profile

  • Enter select mode under Model→ Select. Selected beams/nodes are red
  • Select desired beam(s). In the "property grid" scroll to find "profile" and click the "..." button
  • Either select an existing profile or create a new one. Press "Ok" to confirm selection

Boundary conditions

  • Make sure you're in selection mode (Model→ Select) and select a node
    • In the property grid, press the "..." button to the right of "Boundary condition"

  • For 2D: Rotation and translation out of the plane needs to be fixed. (See picture). This is needed for the system to be solvable

    • Apply load

    • Point load:
      • Select a node
        • If there doesn't exist an node in desired position, select the beam and under Model→ Insert Node
      • In the property grid, input the point load under "Node load"
    • Distributed load:
      • Select a beam
      • In the property grid, input the distributed load.

    Run analysis

    • To run the analysis press "F9"
    • For a visual presentation of result use the "Respons bar" (Lowest toolbar, right side) to toggle axial- and shear-stress, moment and displacement.
