Add source term in species equation
 

I defined three species to form a mixture. In FLUENT, only two species that have less mass fraction will be solved. I want to define mass production or consumption source terms for every species. However, I can only find the option in FLUENT to add mass source term for the two species that have less mass fraction and I cannot find the option to add mass source term for species that has the largest mass fraction. How should I do?

Re: Add source term in species equation
 

At source panel, 'mass' means the last species, which is not solved.

For Fluent 5.x, there is 'mismaching : a kind of bug ?' such that, if I add species mass source, then the last species disappears exactly the same amount of defined source. I do not know the bug was fixed or not.
