a question about initialize in fluent
 
Hi, everybody

Recently, I am doing a project about combustion simulation in Fluent. And I need to use UDF for some detail process. However, after I initialized the species distribution in the initialize panel, I read this data to my UDF by variables called yk in the macros DEFINE_VR_RATE. I found that when I printed the value of yk in the screen for the first step, the value changed. It is not the value that I gave it. Did anyone face the same problem? Or it is just a special precess which administrated by Fluent?

Thank you very much.
