define surface or line source from FLUENT
 

Dear every one,

I am wondering is there any eaiser way to define a surface source from fluent,

or i can only use UDF, while this is not working what i wrote below, could some one give me a hint or example... many thanks

(y=0.3, 0<x<1, 0<z<1):



....loop
C_CENTROID(xc,c,t);

if(fabs(xc[1]-0.3)<=1e-02 && xc[0]>0.0 && xc[0]<1.0 && xc[2]>0.0 && xc[2]<=1.0)


{DO sth....}

...loop
