Hi Peter,

Thanks for the reply.

  1. Noted on that. Hence the buckling analysis in Ansys would only be able to study the shape but not the actual amplitude of the buckling?
  2. Got the idea of how the multiplier works, so the critical buckling load would be the total load I applied in the static structural and at 23.4°C, is that correct? Does the mutiplier shown in -ve suggests not applicable solution? Would like to do a comparison between actual buckling load from simulation and analytical solution.
  3. Yes I noticed it did came out as a warning and the amplitude of the pipe buckling came out differently where it is maximum at the starting and end point of the pipe. I have fixed the total deplacement at the starting and end of pipe and the result makes more sense.
