Notes

This search proceeds by the following 3 steps:

1. A site percolation is applied to uninvaded pores and they are set to trapped if they belong to a cluster that is not connected to the outlets.

2. All throats which were invaded at a pressure higher than either of its two neighboring pores are set to trapped, regardless of whether the pores themselves are trapped.

3. All throats which are connected to trapped pores are set to trapped as these cannot be invaded since the fluid they contain cannot escape.
