Hopefully someone can be able to answer.

I developed a velocity boundary condition based on the Bernoulli Equation. I used the version of fireFoam that comes with OpenFOAM to run a case with my velocity boundary condition and I got the expected results.

I now decided to use FireFOAM-2.2.x to run the same case with the velocity boundary condition. I maintained all the original boundary conditions for the other fields and just changed from PIMPLE to PISO and added the necessary values in fvSchemes. I run the case and I don't get the same results. The pressure is meant to peak and come down including the velocity but it just keeps going up. The fire starts like the case with the normal fireFOAM.

The error is not from my boundary condition because i even changed the boundary condition and used a massflowrate with the table of values and i get the correct results for fireFoam but the same thing happens with fireFoam-2.2.x.

Any advice would be appreciated.
