[gmx-developers] Problem using mdrun

[C.RAMYA]

Hello,

   I am trying to simulate a molecule using mdrun but i am getting an
error after few steps saying :

     "Number of grid cells is zero. Probably the system and box collapsed"

In every step i got some LINCs warning and finally the program is quitting
by giving the above message.i am unable to sort out the real problem of
this.I have tried increasing the grid size but still i am getting the same
message.
Has table-extension got some link with this problem????because table
extension low is also shown.

Please try to help me out....

Thanks.
