Hello all! I tried to run some of my OF cases (solver - fireFoam) for the version 2.2.2 on OF2.3.1 (official version) and found surprisingly different results. On the OF2.2.2 the results of the fire modelling were close to the experimental data. On the OF2.3.1 the same OF-cases run unstable, the velocity fields differ strongly especially near the patches that model the atmosphere and the ventilation, the heat release rate of the fire become higher (with the same massFlowrate of the fuel). On OF2.3.0 all the things were the same as on the OF2.2.2. Is there an explanation of such situation, even e.g. bad gasket between the computer and the chair? Thanks.
