DCGOMG
DCGOMG, DCGOX, DCGOY, DCGOZ
Specifies the rotational acceleration of the global origin.
DCGOX,DCGOY,DCGOZRotational acceleration of the global origin about the acceleration system X, Y, and Z axes.
Notes
Specifies the rotational acceleration of the global origin about each of the acceleration coordinate system axes (CGLOC). 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 DCGOMG command supports tabular boundary
conditions (%TABNAME_X%, %TABNAME_Y%, and %TABNAME_Z%) for DCGOMG_X, DCGOMG_Y, and DCGOMG_Z input values (*DIM) for full transient and harmonic analyses.
Related commands are ACEL, CGLOC, CGOMGA, DOMEGA, and OMEGA.
See Analysis Tools in the Theory Reference for more information.
This command is also valid in PREP7.
