<DIV>Dear users:</DIV>
<DIV> </DIV>
<DIV>When I use FENE (finitely extensible linear elastic potential) to simulate polymers, I always meet a question, that</DIV>
<DIV> </DIV>
<DIV>the distance molecular distance is always beyond the limited value(R0=1.5 or 2.0),</DIV>
<DIV>then the force will be infinte.</DIV>
<DIV> </DIV>
<DIV>In this case how to control?</DIV>
<DIV> </DIV>
<DIV>Thanks for your help</DIV>
