Multi turn coil problem (frequency domain)

Hello, I want to calculatate the magnetic flux density of numeric multiturn coil domain.
I conducted the tutorial mode"multiturn coil asymmetric conductor".
After I conducted that model, I build my model. It's very simple model.
BUT!!!!! I dosen't work.
I build my model totally same like the tutorial model.
Why my model dosen't work? Is any body can help me?
It's very simple model.....
