node connectivity of faces on a surfaces using UDF

Tanjina · April 5, 2015, 23:53

Hello,

Can anybody tell me kindly how can I find the node connectivity of faces on a surfaces using UDF ? All I know is I have to use THREAD_T0,THREAD_T1 macros. Any help will be highly appreciated.

Regards,
Tanjina

What are you trying to achieve? What do you mean by "node connectivity of faces on a surfaces"? You could use F_C0 and F_C1 to determine the neighboring cells and then loop through the nodes of these cells.

I am trying to find Boussinesq's Momentum coefficient (beta= sum(u^2dA/U^2A)). For that I need to velocity of each node and area of faces. From Fluent I can get velocity of each node and coordinates of nodes, but I don't have any information which node is connected to what for making face. For that reason I am looking for UDF which can give me the node connectivity.
