Problem about species source terms
 

Hi, i defined three species and i know only two species equation will be solved in FLUENT. Right now, i defined species mass source term for the two species. My question is whether i need to define the exactly same magnitude source term in continutity equation ("mass source" in boundary condition) in order to satisfy the mass conservation. If not, why is it not necessary?

Hi! You do not need to introduc the third mass source, because Fluent calculates that auotomatically.
