Dear gromacs user,<br><br>I am doing a CNT-water simulation with using ffamber99 forcefield. <br>I don't know what carbon and hydron atom models I should use. <br>In ffamber99.atp, there are a lot of different C atoms with same mass.
<br><br>Can you give me some suggestion?<br><br>Cheers!<br>Bo<br>
