Subroutine Type

Utility/Data Access

Definition

Returns the mass, c.g., and inertia tensor for a body or the entire model.

Use

The function can be called by CONSUB, REQSUB, SENSUB or SEVSUB.

Calling Syntax

Fortran

CALL BODY_MASS_PROPERTY(type, id, cm, mass, ip)

C

c_body_mass_property(type, id, cm, mass, ip)

Python

[cm, mass, ip] = py_body_mass_property(type, id)

MATLAB

[cm, mass, ip] = m_body_mass_property(type, id)

Input Arguments

[string] type

Select from Part, Point_Mass, Flex_Body or Model.  These keywords are case-insensitive.

Note   For type Model, MotionSolve calculates the cm, mass and ip of the entire MBD model.

[integer] id

Specifies the ID of the element of type specified above.

Output Values

[double precision] cm

A double precision array of length three containing the x, y, and z coordinates of the requested element expressed in the global frame.

[double precision] mass

A double precision array containing the mass of the requested element expressed in the global frame.

[double precision] ip

A double precision array of length six containing the six inertia tensors (Ixx, Iyy, Izz, Ixy, Ixz, Iyz) for the requested element expressed in global frame.
