Thanks a lot for your prompt reply. Kindly if you may share any reference material for the FSI modeling for hydrualic fracturing that you had performed. In FSI, did you coupled fluent with transient mechanical or static mechanical? 
Actually, at the moment I am trying to couple transient mechanical with fluent for simulation of hydrualic fracturing. In which, pore pressure from the fluent will be transferred to the transient mechanical for recaluclations of the displacements which will be again transferred to fluent (workflow). 
Yes, I am considering the preexisting elliptical cracks at the end of the sample as shown in below figure. 

I want to extert the pore pressure on the fracture so that I may see the change in the attributes of the fracture (length and width). I have considered two fractures (A and B) propagating away from the borehole. 

If I want to extert pore pressure of fracture from fluent to mechanical, since I am unable to see the modeled fracture (preexisting) in fluent as in below image, how I may select the outlet for pressure in the fluent? If I select the end of the borehole as outlet, how that overall pressure will be transferred in the transient mechanical to be extered specifically on the fracture not on the walls of the borehole. 

 

Thanks a lot for your time and considerations to answer my questions.
