Temp disp study - temp continues to rise when being cooled

Temp disp study - temp continues to rise when being cooled

(OP)
Hello,

I need help with an ABAQUS coupled temperature displacement study. I have attached the loads applied in the input file [https://files.engineering.com/getfile.aspx?folder=...]. The study is mimicking a heating/cooling cycle. Between time 0s and 90s the object is being heated, between 90s and 160s the object is being cooled. Here is a graph of the temperature [https://files.engineering.com/getfile.aspx?folder=...].

My issue is that the object continues to heat during the cooling steps and I can't figure out why. The temperatures across the object are relatively uniform so there is no heat transfer occurring inside the object. The cooling is applied piecewise throughout the object. We are using OP=NEW for each new step, so I do not see why previous heating steps would affect later cooling steps.

Any insights would be welcome,

Thanks.
