ERROR 1 [file solvated.top, line 39]:
atom C1 (Res UREA-1) has mass 0
In urea.itp, no masses are defined. If you correct the format of this file (see
Chapter 5 of the manual), then this issue should be resolved.
Which force field does this urea.itp correspond to? Where should it look
for the atomtypes of urea?
The .atp file corresponding to the force field you are using (ffG43a2). The
atomtypes for urea appear to be generic for use with the Gromos96 force fields.
There are specific atomtypes within ffG53a6 for urea, if you want to use the
newer force field (check the ffG53a6.rtp file for the urea parameters).
