surface reaction UDF-compile
Hi
I have defined a surface reaction UDF I have compiled and hooked this UDF correctly, but I dont know where can I find my reactions in fluent, in the material panel or species transport panel, the parameters of surface reactions are in the default state, Is there any idea? |
Hey!
Reactions are defined as a source term in species transport equations. I suppose that you should look for it in the pertinent zone (in your case wall due to surface reaction) and under source tab and for the relevant species. |
Thanks,
But There is not any source in the source tab, |
Hi, You must setup your reactions by enabling the species transport model. Once species transport is selected, you can then enable volumetric reactions, and then wall surface reactions. Then in your mixture material, you can edit your reaction. Hook your UDF by going to Define menu > User > User Defined Function Hooks. Make sure you also enable the Mechanism for the mixture.

Thanks for your comment, I have defined the activation energy(E) and pre-exponential factor(k0) in the udf, but after hooking the udf, the rection parameters in the species/surface reaction/reaction menu, the reaction parameters (E and K0) are under default conditions, (for example E=8e11) I dont know where is my UDF data? |
