problem Ansoft HFSS v9.2 an optimisation with

Hello

I have a big problem with Ansoft HFSS v9.2
I have tried to do an optimisation with
Optimetrics and after some iterrations,
the programm doesn't stop more!
I have look at all informations, but it doesn't realy work.
It is starting an itteration for the optimisation and it
doesn't finish the step, without message! The CPU is still 99%
used! Why?

I think, you need to install a HFSS 9.2 Service Pack.
