Hi. I have imported the results of transient thermal analysis to transient structural analysis. But the thermal strain I’m getting is zero. The coefficient of thermal expansion is set to reference zero thermal strain at 20C (which is also the initial temperature). For the results of thermal analysis, there is a large difference in the solid’s temperature to 20C. So, I don’t get why I am getting zero for thermal strain (the strain in output control is turned on). <\/p>\n

 <\/p>\n

This is how I imported the body temperature:<\/p>\n

<\/p>\n

I want to get the thermal strain because I want to know when the structural members will fail.<\/p>\n","protected":false},"template":"","class_list":["post-369089","topic","type-topic","status-closed","hentry","topic-tag-3DTransientThermal-1","topic-tag-ansys-transient-thermal-2","topic-tag-strain","topic-tag-structural","topic-tag-structural-nonlinear","topic-tag-thermal-strain","topic-tag-transient-structural"],"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\n\t\t\n\t\t\n\t\t
