Hi, I want to use the REAXFF force field to study the reaction of O3 with water. I read an article earlier that used the force field file“fffield.reax.cho” for O3 and H2O2. What force field file should I use?
You have asked the same kind of question before and nothing has changed since then. My previous response is here: The reaction between ozone and water in the REAXFF force field - #9 by akohlmey
In fact, it is because I checked the information but could not find the relevant I came to ask, I hope the knowledge of people can help me. I believe the Forum is a place that allows people to ask questions that they don’t understand. If I could find it, I wouldn’t have to ask. Why do you have to say“Find it yourself” over and over again? Will the emphasis on modeling pure volume of Water Show your expertise? All in all, this forum gave me a terrible experience. I Won’t speak again. Thank you.
The forum is fundamentally about LAMMPS related questions and not for questions related to specific research fields - for the kind of question you are asking, you need to go out there and read, hire a private consultant or ask your supervisor. This is why people are saying it is your job to figure things out, and not of people in this forum (i.e. they are not necessarily saying this in an aggressive or offensive way). Imagine if someone came up and asked what temperature one needs to consider in order to observe a given phase transition of compound X? That has nothing to do with a bug or functionality of LAMMPS, but rather on your research field.
I think that, if anything, you should save your anger for the person who is supervising you and thus who should be assisting you with that kind of question. Your anger is a bit misdirected here.
But if it serves to make you feel better, this feeling of wanting to set things on fire and run to the hills because you feel like things are tough on your side or that you have been treated unfairly is something we all experience. Sometimes they are valid and sometimes they are just an anger of the moment because we are alreayd exhausted. Currently I have been feeling that towards my french bank, even if I acknowledge that 90% of the current problems are the result of me being too lazy to read and solve burocratic stuff properly. The advice I can give you is to take a deep breath and save your anger for situations that are really necessary and that really apply (and also dont spend it on people that work in french banks in the impulse of the moment, especially if they are women - it will become 600% more difficult to solve your problem).
Hope you chill and that you solve your problem ! Be strong !

What this forum category is meant to be used for is documented in this post: Please Read This First: Guidelines and Suggestions for posting LAMMPS questions
It has “Please Read This First” in its title and is pinned to the beginning of the messages for a reason.
So the main problem here is that you are trying to make up your own rules. That is not going to work. For questions that go beyond the scope of LAMMPS, there is: Science Talk - Materials Science Community Discourse
Because the people responding to questions in this forum category are not your advisers or experts for the kind of question your are asking. How would you justify your choices in a publication or your thesis? “Some dude on the internet told me it was ok to use this.”??
If you are doing research it is your job to identify possible choices and justify them. If nothing else this is something you should be taught by your advisers when being taught how to be a researcher.
That is, of course, your choice. I suspect your chances of finding the help you want in an online forum elsewhere are just as slim as they are here. Remember, those are all communities of people volunteering their time and they all don’t like to do work that is effectively the job of the people asking.
