Hi My name is Dinesh
My research is regarding the Fire & Combustion. In the previous years, I was using Ansys Fluent and FDS, CFD packages for my research purpose. Recently I have started to practice OpenFoam(blueCFD-Core) in Windows. Until now I have practised OpenFOAM (FireFoam) tutorials.
Currently, I am focusing to learn FireFoam simulation. I tried creating my own geometry and mesh based on the tutorial file "smallPoolFire3D" without changing any turbulence or reaction models of the tutorial file. But my simulation fails to predict the combustion for my geometry.
Since I am a beginner I couldn't figure out whats wrong in my input file. I kindly request you to help me with your answers.

Hereby I have attached the tutorial input file and my edited input file also with the predicted images
