createBeam

Defintion

The I and J marker need to be created and passed to this function and a beam element is returned. All three types of beam in MotionView (Arbitrary, Circular and Rectangular) are supported by keyword arguments.

Signature

beam = createBeam(id, i, j, type, **kwds)

Input Arguments

id: ID of beam.
i: Marker I of beam.
j: Marker J of beam.
type: Type of beam. Can be ‘arbitrary’, ‘rectangular’ or ‘circular’.
label (optional): Label of beam.
length: Length of beam.
E: Young's modulus of elasticity.
G: Shear modulus of elasticity.
CRatio: Damping ratio of beam.
AS2: Shear area ratio in the y direction.
AS3: Shear area ratio in the y direction.
OD: Outer diameter of circular beam.
ID: Inner diameter of circular beam.
AS: Shear area ratio of circular beam.
P2_DIM: Y dimension of rectangular beam.
P3_DIM: Z dimension of rectangular beam.
Area: Cross sectional area of arbitrary beam.
I11: Torsional stiffness shape factor for the cross section of arbitrary beam.
I22: The second moment of inertia about y axis of arbitrary beam.
I33: The second moment of inertia about z axis of arbitrary beam.
Fx: Translational preload force along x axis.
Fy: Translational preload force along y axis.
Fz: Translational preload force along z axis.
Tx: Rotational preload torque along x axis.
Ty: Rotational preload torque along y axis.
Tz: Rotational preload torque along z axis.

Return Value

beam: The Beam entity created.
