[gmx-users] External forces

2010-03-03 Thread ROHIT MALSHE
Hi all, 

Can anyone tell me how I can impart external forces on a system - say I have a 
water droplet placed on a tilted polymer surface. With the application of the 
force, the droplet should flow.

That's what the pull code is for.

Hello,
 I am simulating a DPPC lipid bi-layer, and I would like to add an
external force to, for example, one layer of the bilayer.  Do I add
an external force by specifying groups and the acceleration on those
groups in the mdp file?  Is there another way to do this?  Do I need
to alter any other files?


it will work as you propose.



Thanks,
Mike
