Dear Friends,
Thank you for your kind and informative responses. As Dr. Chaban noted, I
checked the density and it was roughly 880 gr.cm-3 which seems low!
I greatly appreciate your further helps.
Most water models underestimate water density, so that is likely a contributing
factor. You haven't told us much about your setup, so it's hard to guess what
you should be expecting. You also haven't said how large your polymer is in
relation to the size of the box, so that could affect the outcome, as well. A
picture showing these "holes" would also be useful, as they very well could be a
PBC effect and thus totally normal. From your description, I was assuming the
holes were within the solvent, but if they are at the box "edges" then likely
what you are seeing is normal.
