Failed to find consistent initial values

Dear all:
I am trying to couple two phase flow and structure mechanics together. In case of generating the huge gap between the initial condition and boundary load ( also inlet), I have already include a step function to eliminate this potential problem. However, it still has this consistent problem. I have also tried step by step, where I start with only two phase flow, phase field and moving mesh which works fine. Dependent on that, I add solid mechanics, where I fixed the interface between the flow and solid structure, and it also works fine. However, when I introduced the moving boundary into the interface, where flow and external load will deform the interface layer, then model goes wrong. Can any one help me to fix that? Thanks a lot. By the way, I also tried with add a point pressure constraint in the model, and it dodes not help.(Hint from previous discussion)
Here is the error:
