CMKE

I/O Options and Subcase Information Entry The CMKE command can be used above the first SUBCASE or within a SUBCASE definition to request component modal synthesis kinetic energy output for all subcases or individual subcases, respectively.

Format

CMKE(format_list,MODES=mset,TYPE=type) = option

Definitions

Argument Options Description
format <H3D, blank>
H3D
Results are output in Hyper3D format (.h3d file).
blank (Default)
Results are output in all active formats for which the result is available.
type <AVERAGE, AMPLITUDE, PEAK>
AVERAGE (Default)
The average of the energy is output.
AMPLITUDE
The amplitude of the energy is output.
PEAK
The peak energy is output. This is the sum of AVERAGE and AMPLITUDE.
mset <ALL, SID, TOTAL>
ALL (Default)
Modal energy is output for all modes.
SID
If a set ID is given, modal energy is output only for modes listed in that set.
TOTAL
Only the total energy is output.
option <YES, ALL, NO, NONE>

Default = ALL
YES, ALL, blank
Modal energy is output.
NO, NONE
Modal energy is not output.

Comments

  1. When the CMKE command is not present, component modal synthesis kinetic energy is not output.
  2. Component modal synthesis kinetic energy output is only available for Frequency Response Analysis (both direct and modal methods). It is intended for use when external CMS superelements are used.
  3. Multiple formats are allowed on the same entry; these should be comma separated. If a format is not specified, this output control applies to all formats defined by the OUTPUT command, for which the result is available.
  4. Multiple instances of this card are allowed. If instances are conflicting, the last instance dominates.
  5. For optimization, the frequency of output to a given format is controlled by the I/O option OUTPUT.
