while i was doing a stress analysis for large dia pipe..
i faced the below problem...

I have provided a loop ( before and after the loop i have
provided a guide with gap of 10 mm)

The bend centre node and To node displacements in the
beginning of loop are unreasonable..there is thermal
displacement of around 30 mm in a centre node and To node of
bend..

The stress levels in the bend is safe...but i am little
bit worried about the unjustified displacements in the bend element.

What would be the reason??? can anybody help me.
