e-core transformer simulation

I want to simulate e-core transformer in model gallery.
Everything worked. But, after solving, graph was wrong.
Induced current and voltage of prim.coil graphs are normal, sine graph,
but graphs of secondary coils are wrong.
There is no curve, only zero state.
What is wrong with it?? I did all thing in the manual.
Please let me know who solve this problems.

p.s. I have comsol 4.3 version. That model was 4.3a ver.
Is it one of the reason??
