I have used genbox for ages but now I need to split a channel 

in the x direction and cannot make genmap recognize the periodic boundary 

conditions. Can a periodic boundary condition be separated by a box? I need 

periodic boundary conditions in x and z. This is my .box:

-------------------------
parameters.rea
-3                    
1                      
# Left box
Box1
-10  -10  -10                
0.000 2.000 1.00                
0.000 2.000 1.00                
0.000 2.000 1.00
P  ,E  ,W  ,W  ,P  ,P    bc's
# Right box
Box2
-10  -10  -10                
2.000 4.000 1.00                
0.000 2.000 1.00                
0.000 2.000 1.00
E  ,P  ,W  ,W  ,P  ,P    bc's

--------------------------

I thought it should be really simple but I cannot get it to work... any help/insight?

Regards,
