`DOMGX`

, `DOMGY`

, `DOMGZ`

Rotational acceleration of the structure about the
global Cartesian X , Y, and Z axes.

## Notes

Specifies the rotational acceleration of the structure about
each of the global Cartesian axes. Rotational accelerations may be
defined in analysis types **ANTYPE**,STATIC, HARMIC
(full or mode-superposition), TRANS (full or mode-superposition),
and SUBSTR. See Acceleration Effect in the *Mechanical APDL Theory Reference* for details. Units are radians/time^{2}.

The **DOMEGA** command supports tabular boundary
conditions (%`TABNAME_X`

%, %`TABNAME_Y`

%, and %`TABNAME_Z`

%) for `DOMEGA_X`

, `DOMEGA_Y`

, and `DOMEGA_Z`

input values (***DIM**) for full transient and harmonic analyses.

Related commands are **ACEL**, **CGLOC**, **CGOMGA**, **DCGOMG**, and **OMEGA**.

See Analysis Tools in the Mechanical APDL Theory Reference for more information.

In a modal harmonic or transient analysis, you must apply the
load in the modal portion of the analysis. Mechanical APDL calculates a load
vector and writes it to the mode shape file, which you can apply via
the **LVSCALE** command.

This command is also valid in PREP7.
