UDF for species problem .
 
Hi all, I am trying to develope a udf for species problem. I need to get species concentration, so when I am using C_YI (c,t,4) to find concentration at a cell I am getting an error. If I use C_YI (c,t,0) I am getting species mass fraction without any error. Could any one help me in this. Am I making any blunder ? Rahul

Most probably there is no 5th species in the domain!

You are correct in eqn C YI(c,t,i) i represent species number not number listed in post-process option. I was taking it different way. We can get mass concentration from mass fraction. Thanks Rahul
