Defines inertia for rigid parts in an explicit dynamics analysis.
Part number for which the inertia is defined (the part number
must have been previously generated using the EDPART command).
The part should be composed of a rigid material (EDMP,RIGID).
Option = ADD, you must input a value; there
is no default. For
Option = DELE or LIST,
to all parts.

The vector containing the global Cartesian coordinates of
the center of mass for the part. This vector must have been previously defined
with a dimension of three (*DIM command) and filled in
as shown below. If
Cvect is blank, the global Cartesian
origin (0,0,0) is used as the center of mass.
Translation mass (no default, must be defined).
Flag for inertia tensor reference coordinate system.
0 (or blank)
Global inertia tensor
(default). You must supply all six inertia tensor components (see
Principal moments of inertia with
orientation vectors. You must supply IXX, IYY, IZZ (see
The name of a vector containing the components of the inertia
tensor. This vector must have been previously defined (*DIM command)
with a dimension of six and filled in as shown below. Vector entries 2, 3,
and 5 are ignored if
IRCS = 1. There is no default
for this vector; it must be specified.
The name of a vector containing the initial velocity (relative
to the global Cartesian coordinate system) of the rigid part. This vector
must have been previously defined (*DIM command) with a
dimension of six and filled in as shown below. If
blank, the initial velocity defaults to zero.
Local coordinate system ID. This coordinate system must have
been previously defined with the EDLCS command. You must
1 (no default).
The EDIPART command applies only to rigid parts (EDMP,RIGID). It allows you to input the inertia properties for the rigid part rather than having the program calculate the properties from the finite element mesh.
This command is also valid in Solution.
