R: RE: [gmx-users] Tabulated potential - Problem

[albitauro at virgilio.it]

Unfortunately, my box sizes are not close to 23. I also carried out calculations switching off PBC or on much smaller systems. 
I received always the same error. 
I tried also a geometry optimization. It finished without warnings nor errors: anyway the potential energy changed only very slightly during the simulation with too large values.

Thanks

This is not nonsense, it is exactly what is says.
The distance between two atoms is more than 10 times as large as your table length.

Maybe you are somehow having issues with periodic boundary conditions.
Is you box size close to 23?

Hi,

I'm trying to carry out a CG simulation and I'm using
a tabulated potential for a bond stretching term.
My MD simulations stops immediately with the error message:

-------------------------------------------------------
Program mdrun_mpi, VERSION 4.0.5
Source code file: bondfree.c, line: 1772

Fatal error:
A tabulated bond interaction table number 0 is out of the table range: r 23.678833, between table indices 12069 and 12070, table length 1020
-------------------------------------------------------

This should mean that some distances are beyond table length (as reported in the manual) but this is
nonsense considering my input files and topology.

Do you have any suggestion?
Thanks!

AM
