I am having a few issues with my UDF for a surface reaction below. I am new to writting UDFs and using Fluent so the help is very much appreciated.
#include "udf.h" #define K1 42.8236 #define K2 41831 #define CH2O 0 #define CO2 1 #define H2O 2 #define NUM_SPECIES 3 #define CH2O_EXP 1.0 #define CO2_EXP 0.0 #define H2O_EXP 0.0 real reaction_rate(cell_t c, Thread *cthread,real mw[],real yi[]) { real concenCH2O = C_R(c,cthread)*yi[CH2O]/mw[CH2O]*K1/(1+K2); } DEFINE_SR_RATE(decomp_rate,f,fthread,r,mw,yi,rr) { *rr = reaction_rate(F_C0(f,fthread),THREAD_T0(fthread)mw ,yi); } This is the error message I am getting when I try to interpret the UDF: cpp -I"C:\PROGRA~1\ANSYSI~1\v140\fluent\fluent14.0.0/src" -I"C:\PROGRA~1\ANSYSI~1\v140\fluent\fluent14.0.0/cortex/src" -I"C:\PROGRA~1\ANSYSI~1\v140\fluent\fluent14.0.0/client/src" -I"C:\PROGRA~1\ANSYSI~1\v140\fluent\fluent14.0.0/multiport/src" -I. -DUDF ONFIG_H="<udfconfig.h>" "C:\Program Files\ANSYS Inc\v140\fluent\ntbin\win64\SR.c" Error: C:\Program Files\ANSYS Inc\v140\fluent\ntbin\win64\SR.c: line 17: parse error. udf limitation: decomp_rate: prototypes must appear outside the function body. mw definition shadows previous definition yi definition shadows previous definition Error: C:\Program Files\ANSYS Inc\v140\fluent\ntbin\win64\SR.c: line 21: parse error. |
