Dear all

As i know if my operating stress are Within Allowable limits but occasional loads (Win 1) are increase and it shows failed. So at that time i will check stress and find out Perticular node where Stress increased .

Compare the displacement with Operating Condition , If it in occ case the displacment in +X direction is supoose 20 mm, but In operating It is 4 mm so i can Provide guide with 4 mm gap which allow the piping displacment within limit.

but
Question 1 - what i can do if my operating case pass with 20 mm displacemnt and In Occ case displacment is lower than 20 mm but its fails so how i can resolve this.

Question 2 is- With same condition expansion case failing.

Kindly reply.
