Eigenmodes in hfss11

Hi all,
I have calculated 20 eigenmodes of a 3d cavity in hfss 11 with the eigenmode solution, then I have plotted Mag_E. field.
Now I wish to plot the Mag_e field for a linear combination of the eigenmodes and not only for a eigenmode at once...
but I dont'know how do it. Can somebody help me?


thanks.

Hfss menu hfss->Fields->Edit Sources
Could it help you?

It doesn't work :(, If I try to set 1 in the scaling factor for two eigenmodes, a warning message occurs that say "Only one mode can be excited for eigen mode solution".

Extract each mode MagE out to file and then use some math code to combine it external.
