Constructor

public interface rigid_body

private pure function rb_init(m, inertia, cg) result(rst)

Initializes a rigid_body object.

Arguments

Type	Intent	Optional	Attributes		Name
real(kind=real64),	intent(in),	optional		::	m	The mass of the body. If no mass is specified, a value of 1 is used.
real(kind=real64),	intent(in),	optional		::	inertia(3,3)	The 3-by-3 inertia tensor. If not supplied, an identity matrix is used.
real(kind=real64),	intent(in),	optional		::	cg(3)	The x-y-z location of the CG relative to the body coordinate frame. If not supplied, the CG is set to (0, 0, 0).

Return Value type(rigid_body)

The rigid_body object.
