Electric Field Pattern in HFSS V.10

Dear All,

I need to know which mode that the HFSS draw when i draw the Mag_E field distribution inside a cavity.

I mean , in an eigenmode problem, after calculating the modes (the resonance frequencies) , i draw the field overlay in the cavity and the drawing is okay
but i need to know which mode does the simulator draw ? is it the 1st. one ? is it the last one ?

Thank you so much
