Normal

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.

Function:

Shell : Pick shell elements to operate.

Segment : Pick segments to operate.
