Dear Seniors, 
I am a graduate student working on hydrualic fracturing simulation using 2way coupling of static mechanical and fluent. 
I have considered a cylindrical geometry with a hole in the center. A pre-existing semi elliptical crack is considred in the simulation. 
How I select the fracture top face and bottom face as a coupling region? As if I select the area A as a coupling region (Figure 1), the sif is highest at the point B and C where as SIF should be highest at the fracture front (yellow circled) (Figure 2). Kindly if you may guide me in this regard.

Hi,

Can you please refer to the thread below and see if you have followed the steps indicated here?

Thank you for your reply Mr. Khemka. 
I have read the shared link. 
I am comfortable in using SMART Crack Growth but I am unable to use that in two way-FSI (Structural and fluent). 
Kindly confirm if SMART Crack growth works in two way-FSI or not? If it is possible if you may share any relevant reference for that.

If you may comment on the posted issue.
