Contours of custom surface rate (UDF and UDM)
Hello everybody,
I want to plot contours of a custom surface reaction rate introduced through a UDF. I know it should be done using defined memory, F_UDMI. I have tried some modifications of the udf routine, still unseccessfully. Can anybody help me on this issue? Thanks! Below is my UDF: #include "udf.h" /************************************************** ********* Custom surface reaction rate UDF ************************************************** **********/ /* CONSTANTS en MKS */ #define LP1 8.4e-5 #define KF 7.e+6 #define densi 1.19 /* Species numbers. Must match order in Fluent panel */ #define ACE 0 #define MET 1 #define NUM_SPECS 3 /* Superficial Reaction (kmol/(m2*s)) */ DEFINE_SR_RATE(my_rate,f,t,r,mw,yi,rr) { real ConACE = 1.; real r1; ConACE = densi*yi[ACE]/mw[ACE]; r1 =LP1*ConACE/(1.7+KF*ConACE); *rr = r1; } |
Hi Cpassa,
Did you resolve this issue. If yes then I would like to know how you had done done it. Looking for your quick response. Thanks in advance |
Cpassa said how to do it: use a UDM. Unfortunately, their UDF does not use any UDM, so we don't know what they tried, and how they failed.
I suggest you do it better: add a UDM to this code, compile it, use it, and share your result (or where it went wrong). It's much easier to help if we can see where it went wrong. |
