Submitted by liulu on

hello:

       I am using pore pressure cohesive elemnt to model hydraulic fracture with abaqus 6.13.  Iwant to export the fracutre opening (or fracture aperture) of the injection point. The PFOPEN(pore pressure opening) or U(Displacement), which is the best to choose.

      Waiting for your answer, thank you very much!!!!
