Just wondering if anyone out there has run thermal simulation verification problems. I am running the "surface to surface radiation" problem and getting some strange results that don't match the help file that comes with it.

Also the help file that comes with it has a formula that looks like something from a my text book but the units don't work out (I come up with Kelvin^4-meters^2, It should be Joules) and the results are off by several orders of magnitude. If someone else has gone down this path before I would really appreciate some pointers.

I have attached an excel file that shows my calculations, refer to the help file for the formula.

I have a simulation running right now so I can't get to the help file, but... you need the Stefan-Boltzmann constant in there to make it work (sigma)=5.67x10^-8 W/(m^2 K^4)

q=A*F*sigma*(Ta^4-Tb^4)
