Hi everyone!

I was doing some comparison between results from OF2.4.0 and OF9 and I noticed that in OF9 the function fieldAverage gives negative values of the variances, e.g. TPrime2Mean.

Have someone noticed the same issue?

I attach an example with the tutorial smallPoolFire3D.

Thank you very much!
