Dear Seniors, 

I am working on hydraulic fracturing using 2-way coupling of Ansys structural and fluent. I am stuck with few sections of the simulation for last 4 months. Please if you may guide me. 

The geometry of the simulation is a cylinder with 54mm dia and 108 mm length with a 4mm hole in the center of the cylinder. 

Methodology: The methdology of the work is to couple static structural and fluent in which the pressures from the fluent will be transferred into structural for the recalculation of the displacements. 
Due to fluent pressure a preexisting fracture propogates in a specific direction. 

Objective: The objective of the simulation to find the (Pressure, crack width, SIF) vs fracture length. The simulation is quite similar to Numerical analysis of fluid-rock interactions in hydraulic fracturing (core.ac.uk) in which author is following the same approach. 

Problem: I have coupled the system sucessfully but unable to find any solution by which I may see the fracture length and width after simulation. 
below are some of the results as follows;
Total Deformation                                           SIF

Kindly if you may propose any solution. 
Developing a dedicated numerical solution for this problem can be a one solution but it will take a lot of time. Since, a author has done the sample work as shown in the above link, so that I expect that there is any thing that I am missing in my numerical simulation.

Hi,

I think you posted similar query here: Hydraulic fracturing Simulation using FSI (ansys.com)
