Hi
I have a problem with Fluent UDF for a mass source term. I'm modelling a catalytic reaction, (steam reforming) with complex reaction system. So I didn't activate the reaction and finite rate chemistry part in the fluent. Just focused on the source terms. So I defined source terms for hydrogen, methane, water,co,co2 and nitrogen. The overall mass source considered zero as we have overall balance in mass. But whenever i enable the UDF and load the library. It seems that Fluent does not consider my UDF for reaction at all. The results are the same as a stream without reaction. Do You have any idea. Thanks Natan Last edited by natantyt; October 11, 2010 at 19:45. |

I also have the same problem.
I found that the source term is not called at all though I had loaded it into the Cell Zone Conditions when I inserted some debug messages in the UDF. User's energy source term can not be called in default. Is there a switch to turn it on? |
