Ansys output ( Deflection ) is varying with change in method of bonded contact/connection. Pls help!

  I have a tank made of Polypropylene, I wanted to perform hydrostatic pressure study for deflection. I got the results. I wanted to validate it. I have few queries in the results. My tank is supported with C channels on the outside, and circular beams on inside. I took tank from Unigraphics NX. Made beams as line body in Ansys design modeller,
  When i performed the analysis first with bonded contact with all program controlled settings. I got solver pivot error for circular beams. When i suppressed the Circular beams and tried for tank with C channel, I got the deflection value. ( no error).

  nnFor validation what I can suggest is to see that you have material, geometry, and loading as per the field/ test setup. You can use Beam formulation. Please see the snapshot below (from Ansys v2020R2 Help) that gives a comparison on the formulation used:nnnnRegards,nAshish Khemkan

  Thank You ashish sir . But can you explain me the significance of radius value in Beam formulation? . Why is there a smaller deflection if we increase the radius value?.Regards,nSundar Rn
