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/time².

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.
