Saw this video at the right time. I am at the first 33 mins of the tutorial, and so so excited. I would wish to give this video a thousand likes. I can't thank you enough!

[@Jacobro02]

I don't understand why it made my brain click, but the way extensive and intensive properties were explained around 17:00 made it make so much sense to me. Such a simple yet effective conceptualization. Bravo

Please do you have more video on LAMMPS and molecular dynamics simulations , if yes , please send me the links to those! Thank you in anticipation.

[@MBauchy]

Many thanks-please subscribe to the channel to get informed when new videos are coming in.

[@gediminasskarbalius3082]

In slide at 1:12:06 you described potentials between atoms that are in different molecules. However, I did not understand how you describe interaction between atoms within same molecule of Si02. Are the lenghts and angles between Si and O atoms are constant (SiO2 is held as rigid molecule) or are there potentials to describe interaction between O and Si atoms within same molecule? And finally, Is there a way to choose one of those options?

[@MBauchy]

Hi-please note that, in this example, we are not simulating any molecule, just individual atoms that interact with each other. 1 = Si, 2 = O. So the Si-O bond length and O-Si-O are not constant.

Thank you for video. Can you calculate the adsorption of an organic compound on the metal surface?

[@ranam]

Can I simulate hydrogen plus oxygen gives water products to reactants with only telling number of Hydrogen atoms and oxygen atoms where the equations satisfy scrodinger equation so the reactants will give this product for checking every chemical equations without memorizing the equations please tell me if IAM wrong simply can I check the chemical equations even the sulphuric acid preparation reactions or uranium reactions or just combine two atoms and can I tell their products

[@loicnasa2]

Thank you for your video. Just one question, why don't you specify any initial velocity for your atoms? Is it taken care of by the NVT equilibration?

[@raashiqishraaq8578]

this was spectacular!!!....more videos please!!...specially how to create potential files....and why the examples in lammps does not have the same format??

[@MBauchy]

Thanks-please subscribe to receive future videos from our group. Regarding the input files used in this video, they have been simplified as much as possible to make it easier to focus on the basics of LAMMPS. Real production input files are typically more complex.

Pure gold! But for some reason command lammps < inputfile does not work on mac termial. I have used lmp_serial < inputfile instead.

Hello Sir, I would like to ask, how to generate data file for Lammps? I am using Materials studio to create the 3D models of some structures and save them as a PDB file. But I couldn't find any process to convert PDB file to data file. If you have any solution, please let me know. Thank you in advance.

[@afzashahid8251]

Thank you so much for an awesome video. Learnt so many things after watching this. Waiting for more such videos on LAMMPS. I have a request. Can you please share the input file so that we can try running this script. Thanking you in anticipation.

Very helpful video for starters. Could you do a tutorial and share the input file so we can try it ourselves too. Another tutorial is requested on how to write a potential file from a given potential equation

[@MBauchy]

Thanks! Some example input files that are ready to run are available on the LAMMPS website. Please subscribe for future videos-we hope to be able to prepare a video focusing on your specific question.

[@kidding686]

You are the only channel I have subscribed to on KZbin. If you are able to make a video describing the potential files it will be very very helpful

First, I am thankful for making such a wonderful videos, which help me to get started with lammps. I tried to follow the procedure but I it showed unexpected end of data file, though the SiO2.data looks similar to yours. Can you help me with this?

[@MBauchy]

Make sure your data file contains the right number of atoms and that the text formatting can be properly read by LAMMPS. Consult the log file to check what LAMMPS can read from the data and what it can't.

[@gideonlyngdoh6454]

Thank you. I am eagerly waiting for another videos tutorials from you guys.

Like as you said, i created SiO2 molecular in Avogadro and then create a data file for 3000 SiO2 molecule. In this data file atoms are neutral. So on running MD simulations LAMMPS shows error for kspace_style as in your example Si and O both have some charges. So my question is, why there is charge on Si and O atom in SiO2 molecule when SiO2 molecule have covalent bonding?
