Streamer Criterion: Global and local computation
Local computation
The local computation involves computing the Streamer inception voltage on a path going from a point of the high potential conductor, to arrive at a point of the low potential conductor.
Two path types exist:
- Defined by the electric field line going from the selected starting point
- Defined by a spatial path
Local computation choice in Flux:
Global computation
For the global computation, user chooses a starting surface and the results give the path having the highest probality to breakdown (path with the highest K value), with the associated Streamer inception voltage value.
In 2D, a starting surface can be defined by :
- Lines
- Linear regions
- Face regions boundaries
Global computation choice in Flux:
