Page 2: Normals (Shell, Segment, TShell Normals)

  • normals panel
  • Figure 1 - Normals Interface

Purpose: This interface is for reviewing and reversing shell, segment, and thick shell normals. Consistent normals in a part may be required to meet mesh quality standards, for contact definitions in LS-DYNA, and also for post-processing shell results at various integration points. Uniformly aligned normals are also required before performing a shell offset operation.

Controls:

  • Entity Type: Select from list (shell/segment/tshell)

  • rbs Show Normal - Use general selection to show elements normal
  • Vector size: Set normal vector size (>1.0 larger)

Clear
 Clear shown normals
  • rb Reverse Normal - Interface to reverse element normal
  • Vector size: Set normal vector size (>1.0 larger)
  • cbc Pick to reverse - Pick element to reverse normal

Reverse
 Reverse all shown normals
  • rb Auto Reverse - Autoreverse normal according to seed element
  • Vector size: Set normal vector size (>1.0 larger)
  • cbc Pick seed - Pick element as a seed for autoreverse

Autoreverse
 Autoreverse normal according to seed element

Done
 Exit Shell/Segment/Tshell Normals interface
