rake ID in UDF
 

Hi,

I try to write data from an unsteady simulation to a txt-file using the Execute_at_end macro. I have a 2D fluidized bed with rakes at different heights. So I want to write data from every rake to a different file. In the Surfaces panel every rake has a different ID. But what is the thread for the rakes? Is it the interior (face thread, ID=11) thread?

The IDs in the Boundary Conditions panel are the thread IDs, right? And the IDs in the Surfaces panel are the face IDs, correct? But how do I identify a rake in the interior?

Or is a rake another thread-type/face-type, because it's identified as a 'rake-surf' in the Surface Types, while the others (interior, wall, inlet, etc) are 'zone-surf' types?

Does anyone can make that clear for me and maybe put an UDF code example in this posting? I'm also using the Eulerian Multiphase model, so there are more than one domain.

Thanks, Sebastian.
