According to the FLUENT manual, I should be able to loop over all interior and exterior cells on a partition using begin_c_loop { } end_c_loop. I should be able to loop over all exterior cells using begin_c_loop_ext { } end_c_loop_ext. However, when I use the first command, my udf only loops over interior cells and when I use the second command, nothing happens. Does anyone know what the problem might be?

I'm using windows 64 platform, is it possibly related to that? I need a way to communicate between to adjacent cells on different partitions. The macros above would make this incredibly easier than looping over individual cell faces.

thanks
