Team, I am trying to have multiple reactions in EBU standard combustion model, but I STAR CD is not allowing me to enter two reactions with same leading reactants. Like H2 + O = OH + H H2 + OH = H2O + H How should I go about this, Regards, Vishal

You can change the second reaction to OH + H2= H2O + H. STAR takes the first species as the leading reactant for each reaction. In the new release of STAR-CD it is much easier to input reactions for EBU model. Check the support group for more information.
