Lab 4: Simulation of water 2: Physical properties of water¶

VMD

Learning goals:

  • To get confident in setting up simple MD simulations

  • To gain experience in the basic protocols applied in MD simulations

  • To learn how to analyze physical properties using MD data

  • To learn how to use Gromacs’ indexing

  • To be able to make simple comparisons between experiments and simulations

Keywords: Molecular dynamics, physical properties, experiments vs simulations, radial distribution function, mean square displacement

Note:

  • You will need to consult the Gromacs manual

  • You will need to search literature for experimental data

  • You will need to estimate how large systems and how long you can simulate on your computer

  • The quantities we analyze are familiar from your other courses. This is how they emerge from real data. We will discuss them during the lectures this week.

As before, have your data and directories clearly organized and ensure that Gromacs is available for you.

The rest of the lab is simple: Pick up the assignment (number 5) from OWL and work throurgh it. The purpose of this lab is the get you going with independent work now that you have learned the basics. These skills will be used in the follow-up assignments as well as in the final projects (some of the analyses will be very closely related). No step-by-step instrcutions are provided.
