I see that some "names" are available online in relation to MD simulation.

  1. VMD
  2. NAMD
  3. LAMMPS
  4. OpenMM
  5. GROMACS
  6. Amber
  7. CHARMM

Are these "names" simulators, visualizers, force fields, or all three?

  • $\begingroup$ I’m voting to close this question because the acronyms of all of these terms could be easily figured out from a Google Search. $\endgroup$ Oct 5, 2023 at 9:48

    $\begingroup$ If you have a specific question, such as "What is GROMACS: A visualizer, forcefield, or simulator?" Then that would be the question to ask. However you have asked several questions in one here, and you're mixing very different things here (e.g. VMD vs OpenMM). I would recommend to do research online before asking your questions here, then whatever questions you have remaining, you ask specifically" rather than asking 7 questions at once like you have done here. $\endgroup$ Oct 5, 2023 at 10:46

VMD stands for Visual Molecular Dynamics, and is a tool to visualize the trajectory from an MD simulation. It also allows you to perform a wide variety of analysis out of the box, and you can also write your own analysis scripts if you Tcl languange.

NAMD stands for NAnoscale Molecular Dynamics and is a package to perform MD simulations on your system of choice. It supports CHARMM and AMBER FF (as far as I know) and you can then use VMD to visualize and analyze the trajectory file.

LAMMPS stands for Large-scale Atomic/Molecular Massively Parallel Simulator and is another popular MD code for performing simulations.

CHARMM stands for Chemistry at HARvard Macromolecular Mechanics is both an MD simulation code and an FF. It is mostly used to model biological systems like DNA(RNA) and proteins.

    $\begingroup$ Regardless, all this information is available from a google search. LAMMPS have a pretty detailed wikipedia article, which is where I got the expansion from. Similarly other codes have a pretty good manual which is available online, and would answer the question. $\endgroup$ Oct 5, 2023 at 10:37
  • $\begingroup$ If that is so, then, essentially, there is no need for this Q&A site. You get all information either in other websites or books. $\endgroup$

    $\begingroup$ My point is that the person asking the question should do due diligence before asking the question. Please see Prof. Dattani's comment below your question. I rest my case. You asked the question, and I gave the answer. Good day. $\endgroup$ Oct 5, 2023 at 11:02
