Leif,
You see, Cosmos, as maybe all software packages, is not so powerful
to tell the truth
So, having solved the flow using the wave Schroedinger's equation
in combination with a potential flow equation and comparing the
results to a computer-calculated results on a coarse mesh, you will
make a big mistake. As far as I know, roughness in CFW is used only
to represent the additional drag, but not the wave generation. So,
due to a very coarse mesh, it is actually assumed that no waves are
created.

you are not alone with such a conversation
You see, the owners of code and mathematics in SW now are in
quarrell, and that's why only the simplest cases can be considered
and solved now by FloWorks. Once I have set up this question here
comprising the Motion 2008, the link is here:
