riteshnw New Member Ritesh Join Date: Aug 2019 Posts: 5 Rep Power: 6	Hi guys... I want to model fire with the mass fractions of oxygen and nitrogen. I can add the mass fraction of oxygen by default and the row for mass fraction of nitrogen is not available. To add the nitrogen row, I have to add air and I can put the nitrogen mass fraction as well. But, when I start the simulation, the error comes up saying that "Error at Node 27: Species air not in thermo database" Can someone please help or suggest me something? Thank you. Best regards, Ritesh
