To All Fluent Experts all over the world,
Thanks you for your assistance in solving my earlier problem. I am now facing another problem. How to write the PDE BC with UDF for mass fraction ? There is a built macro for Div (v)/Div (y). But i cant find any macro for Div(m)/Div(y) where m = mass fraction. By the way, i am going to include it on the wall boundary. Is there any other way to do it? Thank you. From KKLAU |

Hi,
There are not any macros for it. So we have to define the differential equation in UDF. Mass fraction of a species is defined as "C_YI(c, t, 0)". This "0" is the species number in the panel of "Define-Materials-mixture templete-names-edit-selected species". Thanx FJ |

Please define your and what you are trying to simulate a bit more. Thomas
