The DL_POLY_2 FIELD file permits a choice of units for input of energy
parameters. These may be: electron volts (ev); kilocalories
(kcal); kilojoules (kj); or the DL_POLY_2 internal units (10 J mol
)
(internal). There is no default value. Failure to specify
any of these correctly, or reference to other energy units, will
result in this error message. See documentation of the FIELD file.
Action:
Correct energy keyword on units directive in
FIELD file and resubmit.
