Rotary inertia element library

Distributed loads are specified as described in Distributed loads.

*dload

1. Load ID (*DLOAD): ROTA^(S)
2. Not supported
3. T⁻²

4. Rotary acceleration load (magnitude is input as $\alpha$, where $\alpha$ is the rotary acceleration).

1. Load ID (*DLOAD): ROTDYNF^(S)
2. Not supported
3. T⁻¹

4. Rotordynamic load (magnitude is input as $\omega$, where $\omega$ is the angular velocity).
