I need help for how the thermal coupling temperature effect
on deformation analysis.
For example, I solve the study 1 to get results of temperature
distribution, how to input to study 2 deforamtion analysis?
You can do it in the properties of the deformation study.
Right mouse of the study 2 icon and select properties. Go to the
Flow/Thermal Effects tab and check "Temperatures from thermal
study". You will also need to specify reference temperature for
zero strain. If you are using 2008 or before, you will have to copy
the mesh from thermal study to deformation study.
