Modelling connecting lines - 04/02/08 04:08 PM
Dear all,
When I am analyzing a line which is connected to other lines that are not classified as obligatory to undergo stress-analysis (e.g. thin lines), I m facing the question how far in the connecting lines should I extend my model.
I guess the idea is to stop at a point after which the influence of connecting pipes on my stress-analyzed line is practically negligible. My question is what can this point be? Does it necessarily have to be an Anchor or Fixed Point? And what if there is no such a restraint close to my line? Can I consider a restraint such as a Guide or a point with high relative stiffness as the “endpoint” for my model?
Many thanks
