access to a property in a boundary condition using UDF
Can anybody help me to understand what is the meaning of n n n n, in a boundary condition set using a UDF?
For example, who can I change the mass fraction in velocity inlet where there are 3 species?
Thanks guys, I really need your helps.
I would like to help you but unfortunarely I can't understand your first question.
But for changing mass fraction you simply need to enter mass fraction value for each species in species tab of corr. B.C.
Thanks for your response,
I want to write a journal file. So, I want to set values for the velocity inlet for mass fraction and velocity and temperatures at the inlet.
My question is that how I can set the values for them using a Journal File?
Is that clear or you need more clarification,
If you wish to write a journal file which can set the value of your desired parameters at inlet B.C., you should simply perform it once manually, then Fluent will write a journal file containing all of steps you've already made. Remember to Start journal at the beginning of process and when you finished all the steps needed, Stop journal from "Write" menu. I hope it can help you.
