Intepreting Antenna Parameters obtained in HFSS

Any HFSS guru around? I have a problem with intepreting antenna parameters that I obtained from an HFSS simulation. I am perplexed why in some cases, the Radiated power is more than the Accepted power leading to a radiation efficiency greater than 1.0. Also, I found confusing instances where the radiated power is greater than the incident power of 1.0W. How might this have came about? I will greatly appreciate any insight.
Thanks

Hi Waveplumber,

You need to seed the radiation boundary. You get an efficency greater than one because the mesh at the waveport is well-defined, while the mesh in the radiation boundary is not. This will fix your problem.

Thanks savedadogs, I will try seed the mesh and see if that helps Can you you give me quit hints on seeding the mesh?
