Algebraic State
Add an unknown determined by an algebraic constraint.
Add an unknown determined by an algebraic constraint.
Where to find it
System → physics interface → Algebraic State
How to use it
Add this feature under Global ODEs and DAEs. Enter the state, parameter or output expression and its applicable initial value. These equations describe lumped quantities, not a selected geometric domain.
Settings and initial values
| Setting | Initial value |
|---|---|
| Name | z |
| Unit | 1 |
| Residual | z |
| Initial value | 0 |
Result
The next compatible study includes this physical contribution or condition.
Troubleshooting
Check state names, expression units and initial consistency. Algebraic constraints must be compatible with the initial differential states.
