How to specify time-depenant heat source in Heat Transfer Module

Please login with a confirmed email address before reporting spam

Hi, I am using Heat Transfer module and try to specify heat source as a function of t.
It does not accept this in Physics/Subdomain settings.
At the same time I noticed that I can do this if I use general Comsol Multiphysics PDE Heat Equation.
Can anyone help in how to use time-dependent source within Heat Transfer Module?
Thanks

I guess, my question was premature.
I see now that HT module accepts direct functions of t as values of its parameters including heat source.
When I enter functions instead of constant value unit in dialog box becomes red.
This originally made me think that it is an error and I even did not try to run.
Now I ran and I see that it is Ok, just GUI is a little misleading.
