I'm new in User define function. At the moment i'm learning user define function but i don't know how to define variable. How can i get the list of variable using in user define function?.

If somebody have information about list of variable using in user define function,
Please send it to me!

Thank you
Tleja

Thank Sun,

Can i have some more information about this?

Such as, granular Diameter,Molecular weight of species, species mass fraction, etc

please let me know

[Sun]

this is for species mass fraction
C_YI(c,t,i)
and here is a fairly complete list:
