Hi I have a problem,
I'm a new user of COMSOL and I'm working on heat transfer in solids my problem is that the boundary condition "temperature" is not constant it dépends on time (T=a*t+b) and i have to get a curve can you help me to solve that ? thanx

The question of time dependent BCs has been discussed on this forum a lot. One way of doing it would be defining an analytic function. First define parameters (for example)
A: 5[K/min]
B: 200[K]
Define analytic function
Tt = A*t + B
Function definition tab asks for the units of the argument and the function.
In the BC box type Tt(t).
