  • 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
