WEIGHTCHECK

Subcase Information Entry Used to give a report of the mass properties of entire model, including weight, mass moment of inertia and the center of mass.

Format

WEIGHTCHECK(print,grid,set) = option

Definitions

Argument Options Description
print <PRINT, NOPRINT>
PRINT (Default)
Write the output to the .out file.
NOPRINT
Do not write output to the .out file.
grid <GRID>

Default = 0
Grid Point ID
Reference grid point.
Default value defines the origin of basic coordinate system.
set <G, N, F, A, All> Selects the Degree Of Freedom (DOF) set(s):
G (Default)
All DOFs.
N
All DOFs that are not constrained by MPCs.
F, A
Unconstrained structural DOFs.
All
Includes G, N, F, and A.
option <YES, NO>
YES (Default)
Weight check is performed.
NO
Weight check is not performed.

Comments

  1. WEIGHTCHECK must be specified before the first SUBCASE. Mass matrices will be printed out for different GRID sets, namely, G, N, F and A.
  2. WEIGHTCHECK for set N, F and A also gives the percentage change in the rigid body mass/weight with respect to G-Set.
  3. If PARAM, UCORD is defined in the model, the values are printed out relative to the user-defined coordinate system.
