DOMEGA
DOMEGA, DOMGX, DOMGY, DOMGZ
Specifies the rotational acceleration of the structure.
DOMGX,DOMGY,DOMGZRotational 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 these analysis types:
Loads for VT and Krylov methods are supported as long as they are not:
complex tabulated loads (constant or trapezoidal loads in tabulated form are supported)
used in conjunction with Rotordynamics (CORIOLIS,on).
In a mode-superposition 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 file, which you can apply via the LVSCALE command.
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 Theory Reference for more information.
This command is also valid in PREP7.
