I use CST MICROWAVE STUDIO 2008....

(sorry .. my english is poor)

There is a aperture of nano-size on the surface of the metal(gold) and we
emission the plane wave foward to the aperture and observe the Power flow distribution.

(frequency : 309Thz , wavelength : 970nm )

This is what I simulate now...

Not error is occured but the result is not converged at the frequency domain solver
like this....(not mode solver)

-----------
Stimulation with plane wave
Step Residual
0 1.000000e+000
1 3.562300e+039 //(Normally the Residual of Step 1 is order of 1.00e-6 ~ 1.00e-9)
---------
in direct solver(almost same in iterative solver)

and all result has a strange value( 0 or 1.!FFFF )



mesh size is about 2,300,000 ..
OS : XP 64bit
RAM : 8GB

help me plz....T_T
What is the problem?!
