Hi
I am using transient themal stress analysis (ts) to solve a 3D problem in Comsol 4.2. My understading is that in order to compute the thermal stresses inside the material geometry, the ts model must require strain refrence temperature as input. The Strain Reference Tempertaure model input parameter under Thermal Linear Elastic 1 node, however is grayed out in 3D model. It is active only for 1D and 2D cases. I could possibly be missing something. Will greatly appreciate if someone could throw some light on to this issue.
With many Thanks,
R.K.
PS: Regardlesss of this input, the COMSOL is able to solve the problem and generate the temerature and stress distributions.
