Hi my name is Mads and i am a PhD student at Aalborg University in Denmark. I have started to use COULWAVE as i need some tools to transform waves from deep water into shallow water. I tried the example 1D regular waves over step with the version of COULWAVE from 11/2013. My problem is that i get the same results for one layer and two layer and thereby i cannot get the results as shows in the user guide for the two layer solution. I have used the finite difference solver and the Arbitrary level approximation and the exe file in the folder of the example. I hope you can tell me what i am doping S-ringbanen and If you need more information just say so :)
Regards
Mads
