How can I know the veriables name used in Thermal-Stress model

I am currently working on COMSOL 4.0a.
Can anybody tell me how the variables are defined in COMSOL? For example, the three displacement components of u(x,y,z) are defined as ux, uy, and uz. The temperature is defined as .....
Since I want to define a PDE, which is coupled with Thermal-Stress model. I mean in my defined PDE I used the temperature.
Thanks so much in advance.

Bruce,

I believe the displacement components x,y, and z are actually represented by u,v, and w. Temperature is represented by T. When you go to add physics, right click on whatever you want and add it. When you do this the dependent variables and their designations are listed at the bottom of this screen (under "selected physics").

Hi Ted,
Thanks so much for your reply. Yeah, now I know how to define them.
