inhomogeneous XiFoam, problems with "ft" phase inlet
Join Date: Mar 2012

I am simulating the dispersion of a "pollutant" phase in air by using the inhomogeneous mixture of the XiFoam solver (some forums suggest similar approaches). Of course I turned off the reaction.
The case is very simple. I have:
has anyone encounter similar behaviors? is it just a bug of the software?
Thank you in advance

ft does not decrease after combustion (b=0)

In my case ft does not decrease after that combustion occurs (b-->0).
It diffuses and spreads coherently and also the combustion occurs properly but when b-->0 in a cell ft remains with a nonzero value. I expect that ft decreases during combustion and after it becomes --> 0.
Below are my key settings. Modify for inhomogeneous mixtures: fvSolution, thermophysicalProperties and setting initial condition for ft should be enough... but ft does not go to 0 after combustion.
