I am new to OPENFOAM. I am starting to model ammonia combustion. So i selected SandiaD_LTS tutorial and converted ammonia instead of methane and upload different chemical mechanism to it and then run. I did basic changes (Boundary conditions likewise) and run parallel. after running with the reactingFoam i got this error.

Chemistry time solved max/min : 0.04953202103 / 4.837881048e-06
