Which is precisely why Mark is suggesting that you test something simple.  If 
the simulation runs using a normal potential, but fails with your tabulated 
potential, that suggests quite strongly that your tabulated potential is not 
sound.  So you need to go back to something very simple that should have a very 
obvious outcome and scrutinize its success or failure, then move on to something 
slightly more complex, etc until it fails and you identify where the problem lies.
