Hi all,

With reference to my previous post,i have decided to work with volumetric heat source. My current aim is to model a 150m tunnel with cross section area 10m wide and 8m high with a volumetric heat source of 3m x 3m x1m high.

The picture attached below is already in the symmetry of the actual geometry. And the area circle in pink is half of the volumetric heat source.





My aim is to simulate the heat transfer of 4.5MW from the volumetric heat source to the rest of the rest of the fluid surrounding it vie convection n radiation and plot a temperature vs time chart. I tried running my simulation with some initial setting but it seems that there is no heat transfer. Kindly advice if i have make a mistake in my meshing or input settings. Output file is at Post 2.


Advice and help is much appreciated.
Thanks in advance.
