I want to model FlexHose (installed with offset) in CAESAR.

I modelled the flex Hose in two ways.
CASE 1: I modelled the Flex Hose between two nodes, with offset of 50mm at the 'To' Node.
CASE 2: Then I modelled the same Flex Hose between 3 nodes and giving offsets of 25mm each at Node 2 and Node 3.

This is what I observed.
The forces and moments in the CASE 2 (3 nodes) is much less than that shown in CASE1 (2 Nodes) . It seems that when I increase the number of nodes and distribut the offsets amoung these nodes the Forces and Moments caused due to thermal growth/anchor movement seem to decrease.

My question:
Q1: Is it okey if I model a single Flex Hose by splitting it onto more number of nodes. Modelling a flex hose in this fashion seem to give better and more pragmatic results.
Q2: Why is it that increasing the number of nodes improves the results when modelling a Flex Hose.

Thanks in Advance, Anish.
