Hello,
I am not sure what exactly is your "some difficulties".
If you have queries related to drawing the section in the pre-processor
then a little practice should do! If you are thru with your model and if
you have already assigned material properties ..... then in the main Menu
click on Problem and set the frequency value to zero(for zero-slip
conditions at no-load analysis). On the Boundary Condition - if you have
modelled the full machine set the outer most trace(outer periphery of the
stator frame) to a Dirichlet Boundary(A=0). Group the stator
conductors as phase belts. Assign currents to these belts as per 3-phase
convention(I presume it is a 3-phase m/c). Click on Mesh / Create Mesh.
Next Click on Analysis/Analyze. When you are finished with the
Analysis Click on Analysis / View Results.
In your next communication to the group, you may consider attaching your
model so that members could get to know where your problem is wrong !!

Actually I'm trying to use it to perform no load test on induction
motor model but I found some difficults. Someone could help me?
