Karamba3D 2.2.0
New in Karamba3D 2.2.0
These are the new features of Karamba3D 2.2.0
  • "ShellSection"-component for retrieving cross section forces and other results along arbitrary sections of shells (see section 3.6.15).
  • Additional types of loads for beam- and truss-elements (see section 3.2.2). The "Imperfection"- and "Line-Load"-option of the "Loads"-component were moved to the "Beam Loads"-component. The latter are now available as the more flexible "Block"-loads.
  • Line joints for shells (see section 3.4.3).
  • "Cross Section Properties"-component for calculating geometric properties of arbitrary cross sections (see section 3.9.17).
  • Membrane elements (see section 3.1.9)
  • A refined element selection component for retrieving elements via their identifier, color, cross section, material, characteristic length or type (see section 3.1.16).
  • On-the-fly installation via YAK (see section 1.1)
  • Automatic generation of value-lists for several components (e.g. load-case input, degree of freedoms for input at supports,...). See section 2.1.
  • Specification of color ranges via context-menu for the "ModelView"-, "BeamView"- and "ShellView"-components.
  • Rendering beams and shells with cross sections results in watertight meshes with normal vectors pointing outward.
  • Different types of strength hypotheses for bi-axial stress states and differentiation between tensile and compressive strength available for materials (see section 3.5.1).
  • The material database has been enlarged (see section 3.5.3).
  • Physical units of calculation and input quantities can be freely specified (see section 2.3).
  • "Settings"-component to update program options within Grasshopper (see section 3.0.1).
  • "Optimize Cross Section"-component (see section 3.6.8)
    • Cross section design according to Eurocode3: 'SwayFrame'-option added for more economic design of structures where buckling involves no sideways sway.
    • Input 'MaxDisp' can be supplied with a vector for specifying the length and direction component for limiting displacements.
  • "ModelView"-component: Input-plug 'DispDir' lets one specify a direction for selecting displacement-components to be displayed. When supplying a plane, displacements get projected onto it. See section 3.7.1.
  • "ShellLineResults"-component: added display-option 'TransverseShear' for generating principal shear lines. See section 3.7.13.
  • Added 'Dofs' input-plug to "PrescribedDisplacements"- and "Support"-component.See sections 3.2.4 and 3.1.16 respectively.
  • "Shell View": Added cross section rendering without colors. See section 3.7.12.
  • Load-cases identifiers: Names can be used instead of numbers.
  • "JointAgent"-component: the given criteria for joint placement are combined via 'and' instead of 'or'. See section 3.4.2.
  • "LineToBeam"-component: it is now possible to input poly-lines and splines and derive the buckling length from these; multiple names can be given to beams. See section 3.1.6.
  • Import and export of models via Json or Bson (see section 3.8.2)
  • The "Element Query"-component can now be used to get the mass, surface, volume or meshes of specified elements (see section 3.7.3).
  • "Node Forces"-component: Retrieves the truss or beam elements, their cross section forces and directions around a node (see section 3.7.11).
  • In all result-components where formerly only element-identifiers could be input to specify elements for which to get results, the elements themselves can now be used.
  • "Nodal Displacements"- and "Support"-component: node-index or position can now be used to specify the node where to get results. See sections 3.7.4 and 3.7.6.
  • "Beam Displacements"- and "Beam Forces"-component: The position of results along the beam can now be selected via parameter values. See sections 3.7.9 and 3.7.10.
  • Scripting: It is now possible to attach user-data to all Karamba3D objects. See the example 'Karamba\Examples\TestExamples\Scripts\UserData.gh' in the Karamba3D installation folder.
  • Point-masses: The point-masses no longer enter the total mass as output by the "Assemble"-component. In this way it is easier to assess the mass of the structure.
