udf
 

Hi,

I'm working with the UDF and it's quite new for me. I would like to ask few questions: I want to loop on the cells, then on the faces of each cells. For that, it's ok. But when I loop on the faces on each cell, I would like to ask fluent, for each face,the numero of the (1 or 2) cells that are adjacente to this face. I'm trying to use F_C0 and F_C1 or THREAD_T0 or THREAD_T1 with no result. Could someone help me to understand what clearly is a thread..just the set of all cells or the set of all faces?

thanks a lot.
