Anyone used AQWA Wave for Structural loading?

I have attached a simple cylinder with which I ran a diffraction on, the cylinder has a beam element inside which I am using to capture drag, I have created a steering file and ran AQWA Wave, used the output for the structural loading and it appears my drag and inertial forces are 180deg out of phase, thus I am getting negligible total force in the x.

If anyone has experience doing this type of procedure could you please take a look at my files and see if there is any error you can find?

My project can be downloaded from SpeedyShare:

Thanks in advance

 

I have to use aqwa wave for transfering pressures from aqwa WB to static structural in WB and for doing this I need to write some codes.
If anyone has done something like that please instruct me.
I saw a sample of how to write these codes on the internet but I need more information about it.
Thanks
