[ESPResSo-users] ERROR: Interaction range is larger than the local box size

[Clemens Jochum]

Dear all,

I recently updated to the newest development version of ESPResSo and now
my script returns an error when initializing the electrostatic
interaction via P3M method.

My line of code:
p3m = P3M(prefactor = sysParams['electrostatics']['preFactor'], accuracy
= simParams['P3M']['accuracy'], r_cut = simParams['P3M']['r_cut'], mesh
= simParams['P3M']['mesh'], tune = True)

Returned error:
ERROR: box_l in direction 0 is too small
ERROR: box_l in direction 1 is too small
ERROR: box_l in direction 2 is too small
ERROR: interaction range 316.923 in direction 0 is larger than the local
box size 309.423
ERROR: interaction range 316.923 in direction 1 is larger than the local
box size 309.423
ERROR: interaction range 316.923 in direction 2 is larger than the local
box size 309.423

Is there a way to avoid this problem without reducing the number of
nodes ( and thus increasing the local box size?)

Best,
Clemens
