I'm not going to debug the code, but common issues include data being used that's not available and insufficient UDMs being assigned in Fluent (you do this manually). 

As a more general comment, use indents to make blocks easier to read and be careful when assigning number types:

real whatever = 0 ; 

isn't great, 

real whatever = 0.0 ; 

is more appropriate.
