Dear Seniors, 
I am working on hydraulic fracturing simulation by coupling of Ansys fluent and transient structural. 
The work flow (2 way coupling) is: exporting the pore pressure data from ansys fluent to mechanical for the calculation of displacements and stresses (with change in fracture) and again exporting the results to ansys fluent. 
My goal is to study the fracture attributes on the basis of injected fluid pressure and other related parameters. 
Case: A cylinder with a hole in the center upto the 90% depth having a elliptical fracture at the bottom. 
I have some confusions, if you may assist.
1) Do I need to take the injection point at the borehole and fracture boundary as outlet in the fluent for this case (as shown in the below image)? 
<\/p>\n

2) Do I need to add any hydrostatic pressure in the ansys transient apart from the inlet and outlet pressure ranges in the fluent? 
3) Is this possible to run the hydraulic fracturing case without any pre-existing fracture? 
4) What should be the fixed support in this case (for the sample in the image)? As per my understanding, I am going to consider the top and bottom face of the cylinder as a fixed one. <\/p>\n

Thank you, 
Regards.<\/p>\n","protected":false},"template":"","class_list":["post-344614","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
