[交流] 【求助】有没有做过SMD?

2.4. Steered Molecular Dynamics.
An MD simulation
approximates the motion of atoms in a system of molecules
over short intervals of simulated time, typically in the order of
picoseconds to nanoseconds. By adding additional restraints, a
simulation may be steered to observe the possibility of particular
behaviors or to eliminate others over shorter time scales. From
this idea, there is increasing interest in SMD, in which external
forces or restraints are added to the system in order to study
behaviors that might take too long to appear, or to appear often
enough, in an unrestrained MD simulation. Such simulations
have been widely used to investigate the dynamic behavior of
biological systems ranging from identification of ligand binding
pathways33–36 to the identification of intermediates of unfolding
process.37–39
做过的能不能教我做一下。留个QQ号好吗?

SMD 是一种方法,可以用不同的软件实现,比如NAMD。

欢迎到分子模拟论坛NAMD 版来看看
http://www.mdbbs.org/forum-69-1.html



In this section you will learn how to use Steered Molecular Dynamics (SMD).
In particular, you will explore elastic properties and unfolding pathways while
becoming accustomed to constant velocity and constant force SMD simulations
performed by NAMD.
