[Tutorials] heatTransfer tutorial chtMultiregionSimpleFoam

Hi Foamers

I have created a simple tutorial for chtMultiRegionSimpleFoam.

The case is cooling a simple copper coldplate with a single fin using water as a cooling medium.

I haven't been able to find anyone doing cht with water so here you are.

Some special things, I'm using the limitTemperature in fvOptions. It is not really needed but I have not seen it being used so nice to see it IRL. Also added a couple of probe points to see how the temperature in the fin develops.

As always you can find the case here.

Hello Nielsen,

Thank you for your great tutorial! I have learned it and I want to simulate water flowing through tube, but it failed. The water has an inlet temperature of 300K, and the copper pipe is maintained at 500K. I don't know where the "bug" is, because I think my configuration of the case is almost the same as yours. I use the OpenFOAM-5 on ubuntu16.04. The case is attached as follows.https://github.com/QinHao810/OpenFOA...tube_tworegion I am a new FOAMer, could you please give me a hint?

Thank you very much in advance!
