Hydraulic Fracture Modeling with ANSYS

      Hello:


      I am very new to ANSYS and I was wondering if someone has experience with modeling hydraulic fracture propagation with ANSYS. I am also curious to know if ANSYS can model the interaction between the hydraulic fracture and natural fractures?


      Any help would be appreciated.


      Thanks,

      Hello Shashank,


      I don't have experience with modeling hydraulic fracture propagation, but I am interested in learning more about ANSYS material models. I have used a few plasticity models and some students on this site are interested in rock and soil material models. There is a long list of material models in the toolbox, and several models can be combined to build up what is needed.



      Do you have copies of any academic papers on modeling hydraulic fracture propagation?


      Cheers,
      Peter

      Hello Peter:


      Thank you very  much for your response. I see that the ANSYS has capabilities to model fracture initiation and propagation by using cohesive zone elements which I believe should help me to model hydraulic fracture propagation.


      I am a bit curious how ANSYS handles the pore pressure and in-situ stresses in the rock?


      In addition, I am also interested to know how the "Jointed Rock" model works. Does this model creates joints deterministically or stochastically?


      Could you please provide me your email address and I would be glad to send few papers on FEM applications on modeling hydraulic fracture propagation.


      I look forward to hearing from you.

      Hello Shashank,


      Download ANSYS Student 18.2 (not AIM) using the button at the top of the page. Go to Prior Releases at the bottom to find 18.2.  There were some issues with the online help in 19.0 so it would be best to start with 18.2.  Unzip the download file to a local drive and Run as administrator setup.exe. Then you will have a working version of ANSYS that has a limit of 32k nodes+elements. Go to Help and search for Material Reference to see all the documentation on each material model.

      Hello Peter:


      Thank you very much for this information. I sent you an email with few papers on this topic.
