I didn't use hfss before but in CST you could sweep a variable and the graph would show all the patterns belonging to variable values.It is probably the same way in hfss

Thank you fro your reply, if any body have used HFSS answer me and thanks

yes you can do the same in HFSS by changing sweeps

Hello Dear Bukero,
I try to change sweep but no way you mean the sweep of frequency ?
Can you send to me the steps ? and thanks in advance
