Hello,

I am trying to validate my code for hydrogen dispersion using reactingFoam, according to validation model from this study (https://www.sciencedirect.com/scienc...18316616#bib34). When I ran the simulation it seems like the hydrogen dont disperse as expected, but rather behave as heavy gas and stays at bottom of the mesh. I tried to change the direction of the gravity, but nothing happened. Also, when I look at my residuals it seems like the solver doesnt compute density as it is always 0 and when I changed the solver from diagonal to PCG it stayed as diagonal at the log file.

I uploaded the directories to https://we.tl/t-OxlPIUnfwx and I would appreciate some help.

Thank you
