how to keep the flow information before iteration but after initialization?
 

hi, everyone, I want to save the flow information before iteration, but after the initialization,
for example,
C_UDMI(c,t,0)=C_YI(c,t,Index_XL)*C_R(c,t)*MM_YS/(MM_XL*R_YS);
I have tried use these codes in the initialization udf, but i did not work, because the C_YI Micro have not got the value.

Are there any proper way to make this?
