I am trying to simulate a heat exchanger und its heat transfer. For that i have to determine the wall temperature of my pipe. That isn't that difficult. I use a derived value (avererage) for that.
I use that value to calculate a new heat transfer coeeficient in comsol. Therefor i write that temperature in the paramter table in "global definition". Than i start a new simulation and i will get a new wall temperature. I use that new temperature as the next initial value described above.
Now i would like to ask you, if there is a possibility in comsol to define a loop of about 10 steps. Comsol should calculate the wall temperature itself and it should use that temperature for a new run. At the moment i have to do that by hand.
Thanks,
Alex

so far I haven't worked with heat transfer problems, but it seems to me you will need to use LiveLink for Matlab in order to achieve the loop.
Look for modelParam function inside the documentation of LiveLink for Matlab.

I thought something like that. But I have hoped that it would be possible in comsol, because i haven't worked with Matlab so far.
Maybe I will find another solution. If not I have to try it with Matlab.
