Hi,

a quick tip: you can use the  grep command to look for files, variable names etc. in your present directory. 
So you can look for penetrationVolume in trunk/pkg or trunk  like this : In terminal type :  grep -r 'penetrationVolume'  which gives me these results: 

(pyvirtual)dkunhappan@dt-com012:~/yadeTrunk/trunk/pkg$ grep -r
'penetrationVolume'
