HFSS v11 batch syntax

Hi everybody,

I want to launch HFSS simulation in batch mode in v11.
Below is a syntax I use that works:

hfss.exe -batchsolve "C:\Documents and Settings\Administrator\My Documents\HFSS\Tline.hfss"


I'd like to specify a design name within the project.
Is anyone who knows the syntax ?

Thank you for your help
