Iron-loss on three phase transformer

Hello 

I just converted the equivalent model of the three phase transformer in Altair 3D to 2D. but i want to compare the core loss and by theory, they should be same or very close. my question is i i set the current in the secondary to be zero how do i get the current to be inputted in the primary side of the three phase transformer so as to simulate no-load condition.

that is the current should be the magnetizing current and phase. how do i get this? is there a method i can use or a way to calculate it ? i attached a picture of the transformer parameters and dimension
