Description

OMID

<YES, NO>

Default = YES

Controls the coordinate system used by shell and membrane elements for stress and strain results.

This affects the recovery of optimization responses as well as results output to the HM, PUNCH, and OPTI output formats.

Stress and strain results are always output to OUTPUT2 and H3D output formats with reference to the elemental system.

YES indicates that shell and membrane stresses/strains are with reference to the material coordinate system, as defined by the MID/THETA field of the element card.

NO indicates that shell and membrane stresses/strains are with reference to the elemental coordinate system, regardless of what is defined on the MID/THETA field of the element card.
