Ok I try my best...

I want to know, how can i simulate the support condition in the ends of the section of the pipe when separate it of the pipeline?. I mean, i will analyse only a tract of the pipelines for fault crossing. What Kind of restriction would be placed in this case? What grades of freedom should be restricted?

Thanks again
