Communication time out in Fluid-Structure Interaction problem

Hi all,

I am trying to understand the fluid-structure interaction problems. I have tried to run Abaqus example problem (Flow through a bent pipe (FSI)), it is almost running for three days yet to get the result.  I would like to how much time it will take to solve this FSI problem.  

My computer specifications : Processor: Intel (R) core(TM)i7-4790 CPU@3.60GHz. RAM 16.0GB.

In the abaqus command window it shows communication time out as it exceeds 3600 sec.  I would like to know how to solve this issue.

Thankyou in advance.
