What you can learn this way strongly depends on the quality of the questions you ask, and that is where you are falling short, time and again. In order to communicate well with people, you need to have a common ground of understanding and that - as you have demonstrated several times now - is missing and therefore you will get the advice to find yourself a proper tutor over and over again unless you change your ways. In fact, at some point, people will get tired of you not following the advice given and then will likely stop responding altogether.
In your situation, I would not be so eager to dismiss well intended advice from people that have significantly more experience than you. MD simulations are as much a craft as they are science and - like with most crafts - you can really learn its fundamentals only then well, if you are doing it with tutoring from some experienced craftsperson. Otherwise you are doomed to repeat many of the errors (often excellent) scientists have done in the 60+ years since the beginning of MD simulations on computers that have then been pointed out and discussed by the MD simulation community over time. Many of the details are not written down. They are more considered “tricks of the trade” and it is assumed that people practicing MD simulations know about them. Thus text books and publications are only taking you so far, but they rarely contain the practical knowledge of how to correctly set up and execute simulations. My preferred comparison is that to an owner’s manual of a car. It will teach you where the switches and pedals are and what functions they have, but it will not teach you how to drive a car.
If you have not found any of those on your own, you have to improve your internet skills significantly too. About any MD simulation software has a bunch of links to related text books. Also, recommendations have been given in this forum repeatedly.
