Hi Oguz,
Others have answered regarding OPLS. Any recent namd version should work with TIP4P-2005; just use
watermodel tip4
in the config file.

I searched for a tutorial or an example NAMD simulation for OPLS force field, but I couldn’t reach any source. Could you please supply for example namd.conf , parameter and topology files for OPLS force filed ? And I’m also planning to use TIP4P2005 model for water molecules. Which NAMD version do I have to use both for OPLS and TIP4P2005 water model ? Could you please share your experience with me ?
