Hello Im new to COMSOL
I have a 2D model for heat transfer where i like to put following baundaries for the temperature dependent on the time. The time dependent are :
T = 291.15 * (t<5h)
1.4*t+293.15*(5h<t<15h)
325.15 * (15h<t<20h)
325.15-1.4*t * (15h<t<20h)
How and where do i put this into the boundery conditions?

Hi
try to set it on your boundary fixed temperature, then when you run a transient simulation simulation that will scan t for you (you must set-up the range
You can also do a stationary analysis, but be aware that COMSOL considers its internal variable t=0 in stationary, so your time dependent BC's must be set accordingly

Good luck
