I am sorry to ask a novice question again.. Assuming that this equation (I
dw'/dt + [w' cross Iw']= T') is going to be used, all viarables are in the
local frame and the inertia matrix will be aligned to the principal axis.
Since inertia can be represented by a vector, does the Inertia 3x3matrix need
to be generated?
In this case, only variables that have to be transformed from local to global
coordinates (vice-versa) are the angular velocity (w), angular acceleration
(dw'/dt) and torque(T)?
Btw, is this problem with Newton's Damped Law only? Or YADE does not yet
implement the 'accurate' method to calculate the dynamics non-spherical
particles?
P.S. I am interested in this because of the ellipsoid. I'll look at
superquadratics too (after days of deciding). The thing is i'm stuck at
quarternions & rigid body dynamics. <sigh>
Yours sincerely,
CW Boon
