Re: [ESPResSo-users] can not run dpd thermostat and tabulated interaction

The error message might give you a hint: as it says, your box size is too small. Just make it big enough (at least 2x your cutoff).

Hi:

I get the following error message using dpd thermostat and tabulated interaction. I attached the tcl script and tabulated file.

    while executing

"thermostat dpd $temp $gamma $r_cut"

    (file "run.tcl" line 22)

 

What's wrong with this? How can I fix it? Thanks in advance for any useful information.

Best wishes!
