  1. The deformation in ANSYS will match the hand calculation if you have a stress-free boundary condition holding the pipe, have a uniform temperature in the pipe and have correctly assigned the reference temperature and temperature load.<\/li>\n
  2. The reference temperature is set in Engineering Data as a Material Field Variable and in the Isotropic Secant CTE.  The reference temperature is also in Static Structural under Environment Temperature. Make sure all temperature entries use the same temperature.<\/li>\n
  3. The hand calculation won’t match if you use a boundary condition that prevents the free thermal expansion of the material or if the material does not have the same uniform temperature applied.<\/li>\n<\/ol>\n

    <p>You say you used a transient thermal, why? There is no need to use any thermal analysis to match the hand calculation. Use a Static Structural model and apply a Thermal Condition under the Loads category on the Environment tab.<\/p><\/p>\n","protected":false},"template":"","class_list":["post-398458","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
