Привет.

During md simulation of  SiO2
i've got seg fault with sig 11:

Also simulation doesn't go  with any coloumbtype exept Cut-off.
I think, the clue is in fft part of gromacs, but not sure.
Can anybody help me to figure out where the error could be?
Wrong my *.gro, *.top , *.mdp or its a bug in gmx code?
10x in advance.
