Global differential-algebraic system

Understand the Global differential-algebraic system relationship used by Equation contract.

Where to find it

Equation contract → equations

How to use it

Compare the terms, signs and units with your intended physical assumptions before choosing model inputs.

Result

Equation: \mathbf f(t,\mathbf q,\dot{\mathbf q},\mathbf p,\mathbf u)=\mathbf 0,\qquad\mathbf g(t,\mathbf q,\mathbf p,\mathbf u)=\mathbf 0.

Troubleshooting

The equation describes the model assumptions; it is not a separate editable boundary condition. Check the parent physics page for setup and limitations.
