I am new in abaqus and I have a problem in order to solve a thermomechanical problem.Can you please tell how to define the refference temperature in my model?
I tried to but I think my results were wrong because the whole model had the same temperature(the Θ*).
Dear Spyros Asrva
In my knowledge ,for thermal problem, reference temperature very important.So you have to predefine the temperature low as well as high based on your results required.
Yes @Bala Saravanan K but when is used predifined field and set my reference temperature at 297 kelvin for example and after that by setting θ* equal to 713 as a boundary condition in the inner radius my results seems to be wrong cause the whole cylinder has the same temperature 713.
Dear Spyros Asrva
I think the problem is missing some thermal data. Like thermal flim co-efficient, heat flux, and conduction rate.
Bala Saravanan K I inserted all the datas that problem gives.I dont know wahts wrong.Another question(sorry for my silly question),I tried to solve it by hand using 4 Gauss points but my results are weird.I chcecked my calculations and they seem ok.For example,I found the temperature at the middle node on outter radius 602 Kelvin and other two at oute surface 218.Is it possible the temperature at one node to have smaller value than the reference one?(I used the one quarter of the cylinder due to symmetry)
Spyros Asrva The reason behind for temperature vary from one node to another node is thermal conductivity,thermal resistance and energy loss
