I have a sphere with multiple light bulbs (20) that have a combined wattage of 14KW. I am trying to set up my flow sim so the 20 light bulbs have a volume heat source of 20KW within the sphere so I can measure the total temperature in the solid, but it does not seem to be working. The inside of the sphere is considered a white body, but I am really only concerned with what the outside temperature of the sphere is at this point in time.
Can someone take a look and let me know what they think?
So where exactly are you running into issues? Is this going to be an actual physical design? Your sphere is extremely thin, I don't see what is holding the bulbs in place or even how you plan on keeping the sphere from collapsing. Having such a thin geometric feature in your simulation means that you won't be able to get any heat conduction calculations, because in order to get a number of cells across those walls means your mesh will be very fine and your cell count will skyrocket.
