Hi,

well I am using Espresso version 3.2.0, I guess this is the newest version (as 
far as the web-page is concerned).

The strange thing is, that the binary works with the lb_planar.tcl script.  
There, the boundary is a wall, which is moving at constant speed. The command 
"lbboundary wall [...] velocity [...]" works quite fine there! For me, the only 
difference in the source codes are the different kind of constraints (wall vs. 
rhomboid). That's why I don't understand the error message.

Cheers

Markus

What Espresso version are you using? I'm not sure when the velocity BCs were 
introduced, but in doubt, please use the newest or the master from the savannah 
git repository.
