# Version 2.2.0 WIP

### **New in Karamba3D 2.2.0 WIP** <a href="#new-in-karamba3d-2.2.0-wip" id="new-in-karamba3d-2.2.0-wip"></a>

* 'ShellSection'-component for retrieving cross section forces and other results along arbitrary sections of shells.
* Additional types of loads for beam- and truss-elements.
* Line joints for shells
* 'Cross Section Properties'-component for calculating geometric properties of arbitrary cross sections
* Membrane elements
* A refined element selection component
* On-the-fly installation via YAK
* Automatic generation of value-lists for several components (e.g. load-case input, dof input at supports,...)
* Rendering beams and shells with cross sections results in watertight meshes with normals pointing outward.
* Different types of strength hypotheses for biaxial stress states
* Physical units of calculation and input quantities can be freely specified
* '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.
* 'Optimize Cross Section'-component: Input 'MaxDisp' can be supplied with a vector for specifying the length and direction component for limiting displacements.
* 'ShellLineResults'-component: added display-option 'TransverseShear'.
* Added materials to the material data base.
* Added 'Dofs' input-plug to 'PrescribedDisplacements'- and 'Support'-component.
* 'Shell View': Added cross section rendering without colors like in place for beams.
* 'Settings'-component to update program options within Grasshopper.
* 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'.

### Changes that change old definition results <a href="#changes-that-change-old-definition-results" id="changes-that-change-old-definition-results"></a>

* Point-masses are excluded from the calculation of model mass and COG
* Changed coefficient of thermal expansion alphaT for all types of steel material from 1.0E-5 to 1.2E-5 .

### Minor Changes <a href="#minor-changes" id="minor-changes"></a>

* 'ModelView'-component: 'Render Settings'-submenu: upper and lower range for color-plots can now be set independently for '% of range' and 'absolute value'.
* 'BeamView'-component:
  * Added absolute scale for the display of cross section diagrams
  * Normal force diagram: changed color for compression and tension to ligth salmon and light blue respectively.
* 'BeamView'- and 'ShellView'-component: Output of multiple meshes now as one welded mesh for faster display. Can be changed in karamba.ini via 'weld\_shell\_meshes\_for\_output' and 'weld\_beam\_meshes\_for\_output' variables.
* 'Modify Beam'-component:
  * 'Joint'-input added
  * 'lg' input added for specifying the position of external loads for calculating lateral torsional buckling resistance
* Joints: display of stiffness values added.
* Made element-set identifiers secondary element identifiers. This makes element-selection acccording to element-sets possible after model disassembly.
* Added Indian NPB and WPB I-Profiles to cross section library.
