UDF: source, fixed value for a given region

Hi,
If there is any friend here once worked on UDF, source term, please give me some help. It is a 2-D, species transport, laminar flow in a slit. Pure water enters the slit. I want to set a fixed value of species A in the middle of the slit. I can not find a way to let Fluent know this. It can take a UDF for a source term, but not for a fixed value. If I use same UDF, and select "fixed value" in boundary setting for Fluid, then it will give a message saying 'void value expected'. I also tried Adapt-separate skill trying to separate this middle region and specify a species fraction value for it, but after I separated that region, it still belonged to Interior type rather than fluid type, therefore shutting the door of setting value. Thanks for any suggestions. Ming |
