[gmx-users] grompp erros

[Linlin Sun]

Hello everyone,

In order to build a virtual site which is independent from other structure,
I have created a new atom type and set the mass of this new atom type to
zero. However, when I use* grompp*, it failed with fatal errors, which
complain about the zero mass of the new atom type.

Anyone could possibly know how to get around this problem? Any suggestions
would be helpful. Thanks very much!
