Midsurface Thickness Assignment Behavior

Common and solver interface specific behavior for assigning thicknesses to the midsurface.

General

Organize only
  • Creates new components based on the Organization method.
  • Organizes elements into these components.
Contour
  • Creates a contour of the thickness values of nodes and elements, based on the specified options.
  • If you chose Properties on elements, Properties/Sections on components, or Organize only under the Assign thickness to option, HyperMesh honors the Organization method settings during the contour process and the contour value is assigned based on that organization. This allows the contour to match with the applied results.
  • If you chose Elements or Properties/Sections on components for the Assign thickness to option, and choose to use Nodal values for the Thickness calculation method, the values may not exactly match the nodal values that are actually applied. There can be multiple thicknesses associated to a node if it shares an edge with multiple surfaces. Since HyperMesh can only provide one value for the contour, it always chooses the first value which might not match exactly with the applied values in these situations.

ANSYS

Properties/Sections on components – nodal values
  • Creates new components based on ordered nodal thickness values.
  • Creates new properties and sections based on ordered nodal thickness values. Properties are created for those shell elements where thickness is assigned from properties. Shell sections are created for those shell elements where thickness is assigned from shell sections.
  • Assigns the properties or shell sections to the corresponding components.
  • Assigns multiple thicknesses to each property, using real values. In case of shell sections, only one thickness will be assigned.
  • Organizes elements into the corresponding components.
