a question about NLOC

hallo everyone,
Now I have written a User CEL Subroutine, and this Subroutine can run successfuly, but for every interation, it will give me 4 value of NLOC 24000 24000 19800 19800. But in the CFX Pre I can not find this four value. I can just see the number of Nodes and element in CFX Pre of my domain, and they are not equal NLOC.
What is exactly NLOC mean? And how can I see the value of NLOC in CFX Pre or in ICEM?
thanks! :)

NLOC is the number of location in the locale. So say you User CEL Routine is setting a boundary value. For internal processing that boundary will be split into n pieces and your fortran is called for each piece. Depending on exactly what quantity your Use CEL Routine is setting, NLOC could be the number of verticies on the current piece, or the number of integration points, etc. So no, you can't see NLOC in Pre or ICEM.

thanks a lot, stumpy.
Is it possible that we can control through the User CEL to make the boundary not be spilt into n pieces. Because I don't want to get so many NLOC, I just want to get 1 NLOC.
thanks

No! 1 NLOC would correspond to 1 vertex, or 1 IP, or 1 Face Centre. You're likely using the wrong approach if you think you need 1 NLOC.
