HI Every Body

 I am postgraduate student of NavalArchitecture, My thesis is Fatigue Crack Propagation in ship Industry, I want to use Ansys Software for this purpose, at first I generated a plate with a central Crack and did fine mesh around crack and saw the results, for next step I should propagate the crack, my questions are as below:

1. How we can predict the Crack path?

2. how should I growth the crack? shall I clear mesh and extend the crack or.....???? I don't know?

3. How Can I use from Interface Elements?

 Thanks in advance

as you can see in attached, my model has been included too many small area, on the other hand hydrostatic and hydro dynamic pressure are gradient loads, so how we can apply these loads on inside and outside of shell plates as gradient loads?
