Abstract:The 3D parallel analysis system which is used to analyze damage(D)
   evolution of rocks subjected to the hydraulic(H),temperature(T) and
   mechanical(M) coupling processes has been developed.Some details about
   its implementation,linear equations solver,methodologies of parallel
   communication optimization,and efficient approaches for dealing with
   different physical fields are discussed.The results of the test models
   for the HM and TM computing indicate that it is the best
   performance,nearly linear speedup,and more than 82% efficiency to start
   a reasonable number of processors in the system,moreover,the one step
   time-consuming for computing the coupled model of 10 million DOFs with
   default precision is about 200 s.The numerical simulation results of 3D
   hydraulic fracturing process and surface cracks of material caused by
   temperature load have been well reflected the objective laws.The broad
   application prospects of this system have been shown.
