$\mathrm{false}$

useICs

${\mathrm{IC}}_{r\,v}$

[1]

Indicates whether the translational initial conditions are ignored, treated as a guess (may not be enforced), or strictly enforced

MechTranTree

$r_0$

$\left[0\,0\,0\right]$

$m$

Initial displacement of frame_a (center of mass) at the start of the simulation expressed in the inertial frame

InitPos

Velocity Frame

[2]

Indicates whether the initial velocity is expressed in frame_a (body) or inertial frame

VelType

$v_0$

$\left[0\,0\,0\right]$

$\frac{m}{s}$

Initial velocity of frame_a (center of mass) at the start of the simulation expressed in the frame selected in Velocity Frame

InitVel

${\mathrm{IC}}_{\mathrm{\theta }\,\mathrm{\omega }}$

[1]

Indicates whether the rotational initial conditions are ignored, treated as a guess (may not be enforced), or strictly enforced

$\mathrm{false}$

Euler Sequence

$\left[1\,2\,3\right]$

Indicates the sequence of body-fixed rotations used to describe the initial orientation of frame_a (center of mass). For example, [1, 2, 3] refers to sequential rotations about the x, then y, then z axis (123 - Euler angles)

RotType

${\mathrm{\theta }}_0$

$\left[0\,0\,0\right]$

$\mathrm{rad}$

Initial rotation of frame_a (center of mass) at the start of the simulation (based on Euler Sequence selection)

InitAng

Angular Velocity Frame

[2]

Indicates whether the initial angular velocity is expressed in frame_a (body) or the inertial frame. If Euler is chosen, the initial angular velocities are assumed to be the direct derivatives of the Euler angles.

AngVelType

Angular Velocity Frame

[2]

Indicates whether the initial angular velocity is expressed in frame_a (body) or the inertial frame.

AngVelTypeQuat

${\mathrm{\omega }}_0$

$\left[0\,0\,0\right]$

$\frac{\mathrm{rad}}{s}$

Initial angular velocity of frame_a (center of mass) at the start of the simulation expressed in the frame selected in Angular Velocity Frame
