How to display current distribution on the patch in HFSS ?

I would like to ask how to display the current flow on the patch?How to set up n HFSS version. 10. Thank you

Select the patch first and then use the Fiield Overlay option.

I tried to see the current distribution on my patch antenna, but there is no way how to do it. In Help of HFSS says that HFSS/Fields/Plot Fields but there is no plot fields choice in my menu, is there any problem on my version or another thing? It is urgent but I cant do anythingh.
Can anybody tell me how the current distribution will be taken in HFSS v10 step by step?

Did u use interpolate-type freq sweep? This type could not save fields at each freq, and may cause a problem like what u said.
