Adaptive solution, process solver died unexpectedly

Hi users of HFSSv9,

anyone have any idea what could this imply??
"Adaptive solution, process solver died unexpectedly" everytime i tried to anaylse.

I did a validation check and it passed.
But cud it be my problem definition?

I'm trying to simulate a horn; and a cylinder of dielectric at some distance away from the the horn, in free space. All in a same radiation boundary..
Can this be done?? I have no connections between the horn and the cylinder..


cheers

The model you describe can be simulated
I believe there is a mistake in your model
or the port is not correctly assigned...

At moment HFSS is in version 9.2.1
may be you can contact your Ansoft office and get the latest
version of HFSS.

Program could have been terminated by the license server.
Every time you run the model, license server checks if you got a solver module license.

Added after 24 minutes:

I forgot to mention, if license server is a prolem, you will have to re-install the program, but it could fix the problem.
