How to run correctly a three phase power transformer using symmetry

Iñigo Izaguirre

Hello,

 

I am trying to simulate a 220kVA 320/400 Dyn11 power transformer in flux using symmetries because like that I would be able to make a better mesh and also reduce the simulation time. For that I have a full model of the same transformer in flux with the correct results.

 

I have cutted the model in four parts and deleted three of themo to apply simmetry in two planes. I dont have any error so I can make the simulation but the results are totally incorrect. I would like to know how is the proper way to do it because I think Im missing something. I will attach the model here if anyone want to have a look at it. 

incorrect results and the correct ones from a full model simulation

Thank you,

 

Iñigo

Hello Inigo,

 

you defined a tangent magnetic field symmetry on the ZX plane, you need to change it to Normal magnetic field.
