How to know which "mode number" represent actual mode in HFSS?

Hello everyone,
I am using the HFSS program to find the Q factor of a multi mode cavity.
I saw that i can set the program to solve for multi modes but the results are "mode 1, mode2..." how do i know which actual mode each "mode number" represent?
Thanks

Through the field pattern,( E and H filed inside the cavity), you can know the what the mode it is.
