| 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. |
