Altair Forum User

hi..  i want to calculate eigen mode values in feko.  as it is mentioned in the below attachment that the characteristic mode analysis in Altair website only.. but it was not cleared about how to assign and calculate eigen mode values.. as i want to calculate for a eigen mode values for a box(cuboid). can anyone help me...

thank you..

Hi Teju

 

Feko does not have an eigenmode solver.

Characteristic modes are sometimes mistaken for eigenmodes but they are not the same.

Characteristic modes tells you what current modes can resonante at a particular frequency(s) and how strong they would be.

What you seem to require is to know at what frequencies the box could resonate. Feko does not have a solver for this, perhaps CM could be used, but I haven't tried myself.
