I defined several UDF (DEFINE_ADJUST,DEFINE_PROPERTY,DEFINE_SOURCE) in one source files. However,after i complied the source file and hook into FLUENT, i can only see one UDF that is available in FLUENT. Why couldn't i see others UDF in FLUENT?

hi,

can´t answer. can you post your source? then it could be easier to understand...

Following is source terms DEFINE_PROPERTY(cell_density,c,t) {

real density;

density=2967.7679;

return density; }

DEFINE_SR_RATE(my_rate,f,t,r,mw,yi,rr) {

*rr=1.03643e-4; }

DEFINE_SOURCE(species_K,c,t,dS,eqn) {

real K_source;

K_source=C_UDSI(c,t,14)+C_UDSI(c,t,15);

dS[eqn]=0.0;

return K_source; }

Please take a look. I don't know if there are some problems with C compiler in our systems. I guess there are some confliction between different edition.

it is working, but only with: #include "udf.h" at the beginning ...
