<P><B>Description:</B>
|
|
</P>
|
|
<P>Define a computation that calculates the total rotational energy of a
|
|
group of granular atoms.
|
|
</P>
|
|
<P>The rotational energy is calculated as the sum of 1/2 I w^2 over all
|
|
the atoms in the group, where I is the moment of inertia of a
|
|
disk/spherical (2d/3d) particle, and w is its angular velocity.
