But also the other modes are not very good. The reason is: Since we have only a single symmetry plane left (z=0), we have to compute in a volume that is four times as large as the volume before. In such a large volume, there are much more modes than 15 in the frequency range from 0 to
estimation
(we specified
an estimation of 2GHz).
We could say that we want to have more solutions
, but that would
drastically increases our memory consumption.
Since we are using already about 200 MBytes
(our grid contains 1.2 million gridcells), we do not want to do this.
We could try to compute with the single precision version of
gd1, single.gd1, then we could compute 30 modes in 200 MByte.
Instead we adjust our estimation
to 1.2 GHz.
The end of our inputfile now is:
