lreverse

Mapdl.lreverse(lnum='', noeflip='', **kwargs)

Reverses the normal of a line, regardless of its connectivity or mesh

APDL Command: LREVERSE status.

Parameters:

lnum

Line number of the line whose normal direction is to be reversed. If LNUM = ALL, the normals of all selected lines will be reversed. If LNUM = P, graphical picking is enabled. A component name may also be substituted for LNUM.

noeflip

Indicates whether you want to change the normal direction of the existing elements on the reversed line(s) so that they are consistent with each line’s new normal direction.

0 - Make the normal direction of existing elements on the reversed line(s)

consistent with each line’s new normal direction (default).

1 - Do not change the normal direction of existing elements on the reversed

line(s).

Notes

You cannot use the LREVERSE command to change the normal direction of any element that has a body or surface load. We recommend that you apply all of your loads only after ensuring that the element normal directions are acceptable.

Real constants (such as nonuniform shell thickness and tapered beam constants) may be invalidated by an element reversal.
