Fluctuating residuals in transient simulation (transientSimpleFoam)
I modified the transientSimpleFoam to add a temperature equation and tried to run a case of t-junction from pimpleFoam tutorial with the exact same boundary conditions. The residuals I get, fluctuate a lot as shown in the figure: http://img21.imageshack.us/img21/6919/screenshotepd.png
The fvScheme is as follows:
fvSoultion is as follows:
The boundary conditions are exactly same as that in pimpleFoam case with T at inlet =400K and everywhere else is 300K.
Why is there so much fluctuation in the residuals??
I figured out that I was plotting residuals incorrectly. My bad. Sorry!!
