Hello everybody!

Recently I am trying to modified the reaction rates when using the EDC model in fluent. The UDF manual of fluent shows that I can implement that by using DEFINE_NET_REACTION_RATE. And here is the example provided in the UDF manual :

#include "udf.h"

DEFINE_NET_REACTION_RATE(user_net_reaction_rate, p, temp, yi, rr, jac)
{
int i;
for(i=0;i<n_spe;i++)
rr[i] = 1./(real)n_spe - yi[i];
}

However, in my own scheme I need to call the viscosity of the current cell and I will use the macro C_MU_L(c, t), which means I need to know the information of the current cell and thread. But this reaction rate function does not providing the information. How can I solve this problem? or how can I acquire the cell and thread information when I use DEFINE_NET_REACTION_RATE?

Any suggestions will be appreciated. Thank you.
