Default Defining contact regions in FSI problem.!!!

sreemvlk is on a distinguished road
I am doing a Two way FSI problem using Transient structural and CFX in Ansys Workbench 14.0,..The problem is to study the interactions of a flat plate placed horizontally and axial water flow over it..
There are 14 faces of the solid of which 4 of them are fixed...and two of them acting as the interface..I know how to do the setup.

But i am facing a problem in defining the contact regions between solid and fluid.
I am not getting the result with default contact region..Do I need to cancel the default contact region and make new ones,,,??
If so, does the contact region should be the same as "interface" between solid and fluid where the data is interchanged??..
Please help..
