heat transfer in non linear system by using time dependent temperature function

Hi,

I am solving a heat transfer non linear problem in COMSOL v3.5a.


The problem is a rectangle geometry in which a left side heated with time dependent temperature function when time is zero at temperature 25˚C, then as time is increases upto 50s the temperature also increases upto 30˚C.


With this I am using time step range 0.1 with relative tolerance 0.001, and absolute tolerance 0.00010 and linear system solver: Direct (SPOOLES), method : generalized alpha, time steps by solver :Free.

I solved the problem also. Here my question is how to used a time marching scheme in COMSOL for each time step for a left heated side which used a time dependent temperature function so that I can control the temperature with time.

Can anybody send a reply please..

Thanks a lot a lot in advanced.
