Somebody can help me?

I have HDPE pipe with diameter - 900mm and length - 150 meter lay on the ground. I create the material and turn on Bourdon effects for PE pipe.
The question is how i input ground friction? May be i need use the Underground pipe moleler (but the pipe lay on the ground)?
The pipe have snaking (lateral deflection)when temperature increase. And i want to know the value of lateral deflection when pipe is guided.
What the right way model this situation?

Thanks,Oleg

This program will not help you. It is a beam element program unable to determine buckling interactions such as the squirm you wish to investigate.

Bourdon effects pertain solely to Elbows...

Overall I would say that your questions indicate a lack of fundamental understanding that is required to use the software correctly. I suggest you study up on some of the newsletter available free for the downloading from COADE...

Also I suggest you use the search function to research a specific topic you are not the first to enter this forum with question in hand many have been before you and many will come after you....

If you have some sort of anchorages near the ends of 150 meters of polyethylene pipe just laying flat on the ground, I doubt that "ground friction" will offer much impedance to resulting "snaking/lateral deflection". While it is also a function of end restraints, my guess is your resulting layout behavior will perhaps be more a matter of geometry with thermally increased curve/arc length(s) and off-sets etc. (due to a coefficient of thermal expansion/contraction of the plastic piping maybe 15-20 times greater than that of ductile iron or steel pipe etc.) than it is ground friction. In this regard, it also may not take much increase in arc length to result in a LOT of lateral movement in some cases.
