Load-flow Algorithm used By SIMULINK for 3-phase Unbalanced load

Hi, Can anybody tell me what is the algorithm used by the SIMULINK to analyze the load flow in a 3-phase unbalanced power system?

Here they have written about the tool used in SIMULINK for load flow , but no information regarding the algorithm.
