How to set report type when monitor gas temperature inside cylinder?
 
1 Attachment(s)
Hello All,

I'm doing a 3D case to simulate the cylinder in a compressor...I need to monitor how the gas temperature change in cylinder along with the piston moving... I find that when I choose different report type, the temperature curve is quite different.
For example, when pressure drop to 0.63bar, the gas temperature is like the below:
1.mass weighted average: 28.47℃
2.area weighed average:28.50℃
3.facet average:32.16℃
4.vertex average:40.01℃

I'm confused about these results... Which one is more suitable for my case?

It will be greatly appreciated if anybody give me advise on this problem...

Thanks
Ellen
