[cscfx]

hello,everybody,i want to implant a transport equation to CFX, and i add a additional variable to CFX,and the source terms of the transport equation are related to variables of CFX,such as velocity,volume fraction,density.etc. so i write the sources by Fortran language,but i did not know how to calling the variables(such as velocity,volume fraction,density),anybody can give me some help? thanks a lot! I've been puzzled by this question for a long time. i sincerely hope you can give me some helps!
