[gmx-users] Is the new version of Gromacs going to be able to do implicit water md?

[Arthur Roberts]

Hi, all,

I know this question might seem almost heretical because I am aware of  
the issues with implicit water md.  I actually prefer explicit waters  
because I think it more realistically represents the water  
environment.  However,  the problem with explicit waters is that the  
calculation is time consuming.  I am collaborating with industry and  
we need a relatively rapid way to do MD that doesn't require a  
computer cluster.  Therefore, I was wondering if Gromacs 4.0 will be  
able to do implicit water calculations that will significantly speed  
up the calculation?  I know the previous version didn't.  Your input  
is much appreciated.

Best wishes,
