FEM analysis of a spring

Hi all,
I've designed a spring and I want to see if the value of tensions are, more or less, the same I've calculated with the formulas.
The matetial is "springflex" with
E=206000 MPa
G=81500 MPa
Su=2270 MPa
d=0.9mm
In my calculation, the spring is verified.
Anyway, the results that Mechanica gives me (I've used WF5 for the FEM simulation) provides tensions much much high...
I've done two tipe of analysis:
1) I've imposed the displacement (35 mm)
2) I've imposed the force (25 N)
but, for me, the results are incorrect but I don't know why.
I've tryed "linear" and "non-linear" analisys for with large deformations.
Greetings
