Hello!
Thanks for answer.

It is familier to me too :)

I have not found out anything similar.

Okay, no problem. As soon as I willl finish with it, I will necessarily 
submit.

I have attached all sources files (and scene.xml) to the previous letter:

rename attachment-0001.bin to  gram-yade.tar.gz.

I wish to make export of data to a format silo (hdf5) to process and to 
visualize them by means of VisIt (http://www.llnl.gov/visit/home.html)
To export data into the silo format them it is necessary to consolidate in the 
arrays which then to save in a file. 
Engines are necessary for сollecting demanded data  about bodies. After these 
engines will bypass all bodies and will collect the demanded information, 
they should submit a signal on export of data. Thus, it is required 
CompoundEngine with functions preaction() and postaction() and vector of 
engines. It if in brief.

Thanks. 

ps.

>my wife is finishing her PhD 

Successes of yours wife! :)
