[gmx-developers] Semantics of acceleration groups.

[ramon at juguete.quim.ucm.es]

Hello, I am playing with Gromacs code in update.c

What is the semantic of acceleration groups?

Looking at the code, it seems that the scaling effect of barostats
and thermostat is not applied to the velocity of the accelerating group.
This velocity is discounted before performing any other operation.
 
Why?
