how to implement some equations
 
i need to implement some equations in fluent. this equations i dont know if are the same fluent uses, but i need to use a premixed combustion and i must use the equations that i have in a paper. how to do it?

Most likely you have to incorporate them as a User-Defined Function (UDF) I think. Do you have access to Fluent users service? I think that there is a similar problem to yours in the tutorial pages and the udfs help.

thanks for your answer. I dont have access to this documents. Do you have it to send to me?

Try to seek access from your institution (if you're at university) or the IT technician (if you work). Otherwise in the Fluent window go Help and choose index, user's guide, there should be plenty of information on premised combustion with examples and theory... maybe you'll find that you don't need to write the equations after all!

I'll try to find a sample udf so you can get an idea. Unfortunately, combustion is not my interest so I know little about it, but just try the above and let me know if it goes.

ok. there no example about premixed, but i am trying to change the example about other equations implementation.

actually do you have an udf with other kind of equations implemented? so i can take a look on it...
