PrescribeInitialEquilibrium

Prescribes initial equilibrium state aka zero initial velocity and acceleration to the associated connector.

Usage

PrescribeInitialEquilibrium()

Connectors

• flange - (Flange)

Variables

Behavior

\[ \begin{align} \mathtt{flange.f}\left( t \right) &= 0 \\ v\left( t \right) &= \frac{\mathrm{d} \mathtt{flange.s}\left( t \right)}{\mathrm{d}t} \\ a\left( t \right) &= \frac{\mathrm{d} v\left( t \right)}{\mathrm{d}t} \end{align} \]
