Fluid structure interaction for a cantilever undergoes fluid effect

Dear all,

I am encountering a problem of using fsi model. Basically I looked at the model Comosl provide, it's model ID 987, the instruction they provide is based on comsol version 3.5. Howver I am using comsol 4.1 also 4.2. So I am trying to create the same model but using just a cantilever (prismatic beam) insead of that complex geometry, also I am using fsi module. But I don't know what's is wrong with my model.

One problem I found is due to solver difference. The other might due to boundary conditions I am using.

I am uploading this file so can any one look at this and help me with some solutions?

Thank you in advance.

I am also uploading the model ID 987 the comsol provides
